v2.6
I would like to be able to make arbitrary changes to my database's schema without needing to delete all the data. I would like to be able to write module code to migrate the data from the old schema to the new one.
The request will return to its prior live status.
Pick the request that Manual migrations is a duplicate of. Energy rolls up into that request and GitHub closes the linked issue as a duplicate with a timeline reference to the canonical.
Restore as an independent request. The linked GitHub issue will be reopened and its duplicate-of relationship cleared. The original timeline entries stay as history; the note below is posted as a follow-up comment.
