Mm upgrade to 7.3.0 failing with SQL error

Looks like you have ANSI_QUOTES enabled, which is not supported by the DB migration script.
Is there any specific reason why you have that enabled?

There are several ways to work around this issue now:

  • Disable ANSI_QUOTES globally
  • Manually run the migration with a modified query
ALTER TABLE Configurations ADD COLUMN SHA char(64) DEFAULT '';
  • Find out how to disable ANSI_QUOTES only for the mattermost connections to this DB server (if it hosts other applications too)
