I currently have, in SharePoint 2013, a document library with three workflows. I had to break a complicated, single workflow into three because it was way too big. The primary workflow is started manually. As it completes, it starts the second. The second starts the third. Using the Start Workflow action, I pass variables from one workflow to the next. I also use Store Data and Retrieve Data actions to pass collections between the workflows.
I need to migrate the whole system to our O365 tenant. Luckily, I have ShareGate. Unfortunately, the Start Workflow and Store/Retrieve Data actions aren't supported for migration.
Can someone here give me details on how I can achieve the same functionality in O365... starting consecutive workflows and passing variables and collections from one workflow to the next, please? I need to get this going quickly and I'm not finding much on the forums.
