Step 1: export everything first
Before touching anything else: scheduled and drafted posts with their dates, original quality media, evergreen captions and hashtag sets, and any historical reports you might need for clients. Do this while your subscription is fully active, because access has a habit of shrinking the moment you cancel.
Step 2: connect accounts in the new tool
Accounts do not migrate; permissions are granted per tool. Connect every account for every client and grant every permission asked, because a skipped checkbox creates a half working connection that publishes text but fails on video. Check the load bearing details while you are in there: Instagram accounts professional and linked to their Facebook Pages, admin roles held on Facebook and LinkedIn Pages.
Step 3: one test post per platform per client
A real published test, not a saved draft. It can be a harmless piece of evergreen content. Five clients on five platforms is 25 tests, and it is the best hour of the whole switch, because every weak connection reveals itself on a test instead of on a client's launch post.
Step 4: the overlap week
The old tool finishes the week it already owns. The new tool takes over from Monday. No content is rebuilt in a hurry and no deadline rests on a day old connection. At the end of the week, confirm everything published, then cancel the old tool.
Step 5: watch the first fortnight
New connections are at their most fragile in their first weeks, as tokens settle and permissions get exercised for the first time. This is where your new tool shows its character: SocialPro monitors connection health continuously, checks each post before its slot, confirms delivery with each platform, and alerts you instantly with a one tap retry if anything fails, which is precisely the safety net a migration fortnight deserves. If you are switching because posts kept silently failing, that guide below explains what was going wrong.
