Salesforce Chatter migration can often hit a wall because a Chatter feed's meaning lives not only in its text, but also in its associations. FeedItem and FeedComment records point to parent records, authors, and mentioned users that do not exist in the target org. Migrating Chatter means rebuilding every one of those references before the feed loads.
A Salesforce-to-Salesforce migration can go wrong in many ways, but the stakes can rise significantly higher when it reaches Chatter. Migrating the collaboration layer, feed posts, comments, mentions, and attached files linked to records across the org, often causes projects to stall, extending timelines or, worse, produce disconnected content that looks correct until someone opens a record.
The very same challenge emerged in a project when a leading global media and entertainment company tried to migrate its Chatter and file data between orgs but their first tool of consideration, Informatica, showed its limits. That's when they opted for conemis.
This article explains why Chatter resists standard migration, what a correct Chatter migration actually involves, where Chatter stands as a Salesforce feature in 2026, and how conemis transition cloud (ctc) moves the collaboration layer with its history intact.
Read where Chatter sits among the six Salesforce objects that break migration projects.
Chatter migration breaks projects because a Chatter record carries almost no value on its own. A FeedItem is a row of text whose meaning comes entirely from what it points to: the parent record that the post sits on, the user who wrote it, the colleagues mentioned in it, and often an attached file. FeedComment, the reply object, points back to its FeedItem and adds its own author and mentions.
Export those records with a tool built for flat sObject loading and every pointer breaks at once. The parent ID belongs to the source org. The author ID resolves to nothing. The @mentions reference users that may not exist in the target, or that exist under different IDs. Salesforce offers no standard migration path for feed data, so other migration tools do one of two things. They either skip Chatter entirely, or load Chatter text while the associations, authorship, and thread context around it never arrive. The second outcome is the one that damages a project, because the migration reports success while the collaboration history arrives orphaned.
A correct Chatter migration rebuilds every association before the feed records load, in a specific order. The work breaks into three parts.
The first task is mapping. Before a single FeedItem loads, the migration has to resolve each reference it carries against the target org: which target record is this post's parent, which target user is its author, which target users do its mentions point to. This is not a lookup that a flat export performs. It requires holding the source and target object models together and translating every ID from one to the other. ctc handles this by mapping Chatter feeds to their parent records in the target org as a built-in step, so the references are resolved before the load runs rather than patched afterward.
A Chatter feed is also an audit record. The original author, the date a decision was discussed, the people pulled into a thread, all of it carries operational and, in regulated sectors, compliance value. A migration that loads feed text under a single system user and a single import date destroys that record. The published media and entertainment project made this explicit: preserving the integrity of the Chatter and content layer was a non-negotiable project requirement, not an optional scope item. ctc carries original authorship, mentions, and timestamps through to the target so the feed reads in the target org as it read in the source.
Chatter and files are one problem, not two. Posts carry attachments, and those attachments are ContentDocument and ContentVersion records with their own ownership and sharing logic. Migrate the feed and the files in separate passes and the attachments arrive detached from the posts that referenced them. ctc processes the full content layer, feed records and their files, alongside standard data in one controlled, traceable workflow, so a post and its attachment land together and stay linked.
conemis migrates Chatter by treating the collaboration layer as a first-class object scope with pre-built transformation logic, not as a bespoke mapping exercise built under project pressure. The transformation logic for Salesforce content objects is built into ctc through native Salesforce connectors designed for content and collaboration objects. That design choice has a direct consequence for project teams.
In the media and entertainment migration, the client's own team ran the migration after three hours of training and enablement from conemis. The complexity of the Chatter object model was absorbed by the platform rather than transferred to the team as a configuration burden. Every Chatter feed, file, and attachment arrived in the target org intact, correctly associated with its parent record, and immediately usable.
In a separate Service Cloud org merge for a German automotive and industrial supplier, Chatter was included in a migration scope that also moved 1 million email messages, 40 GB of email attachments, and 2 million records in total across 10 objects and 200 fields, per conemis project data. The project was delivered on time, scope, and budget, with Chatter handled as part of the managed migration rather than as a problem deferred to the end.
With the Salesforce Summer '26 release, Chatter is disabled by default in all new Enterprise, Unlimited, and Developer Edition orgs while existing orgs are unaffected. New orgs are now provisioned with a Slack workspace, and Salesforce Channels configured out of the box as the primary collaboration surface.
Salesforce has not announced a retirement date for Chatter, and there is no indication that existing orgs will be forced to move away from it. Features that depend on Chatter, including Case Feed and certain Experience Cloud sites, continue to function and can be enabled in new orgs through Setup. But the direction is clear: Salesforce is investing in Slack and Salesforce Channels as the collaboration layer going forward, and Chatter is being de-prioritized.
For organizations planning a Salesforce migration, this shift adds a layer to the scoping conversation. The Chatter data that lives in an existing org, years of feed posts, comments, mentions, and attached files tied to records, still has to be migrated correctly regardless of whether the destination org will continue using Chatter or transition to Slack.
ctc migrates Chatter data independently of whether the target org has Chatter enabled by default or activated manually. The migration scope, the reference resolution, and the association preservation all work the same way. For organizations moving away from Chatter entirely, ctc also supports a Chatter to Slack migration, preserving the feed history and associations as part of the broader transition. The platform change does not affect how ctc handles the migration. It affects why getting it right matters more now than it did a year ago.
Yes, but not with a flat export. Chatter feeds carry associations to parent records, authors, and mentioned users that all reference source org IDs. A correct migration resolves every reference against the target org before the feed loads. ctc handles this as a built-in step through its native Salesforce connectors.
It depends on the approach. Migration projects typically load feed text under a system user with an import timestamp, which destroys the original authorship and date context. ctc preserves original authors, mentioned users, and timestamps so the feed reads in the target org exactly as it read in the source.
Data Loader processes one object at a time as flat sObject rows. Chatter's value lives in multi-directional associations across FeedItem, FeedComment, parent records, users, and attached files. Exporting those as flat rows breaks every pointer. Rebuilding them manually is technically possible but carries high error risk at scale and requires extensive sequential operations that most project timelines do not account for. See how Data Loader compares to ctc across a full migration.
Salesforce has not announced a retirement date for Chatter. With Summer '26, Chatter is disabled by default in new Enterprise, Unlimited, and Developer Edition orgs, but it can be re-enabled manually. Existing orgs are unaffected. The shift signals that Slack and Salesforce Channels are the strategic direction for collaboration, but Chatter remains available and functional for orgs that depend on it.
Chatter is where institutional knowledge accumulates: the decisions, approvals, and context tied to live commercial relationships. A migration that loses it has not finished the job, however clean the straightforward data looks.
ctc migrates the full Salesforce content layer, feeds, files, and attachments, with associations and history preserved.
