@BeAware you might be able to do this via a 2 step migration:
Firstly migrate to an instance at temp.beware.live. Then do a self destruct on your old instance. Importantly wait for all sidekiq jobs to finish afterwards. This may take hours, days, or weeks.
Finally set up a new instance on your domain and migrate to it.
This may or may not work, so do at your own risk, but this is the only way I could conceptually imagine it might work. I’ve never heard of anyone actually attempting it, though, so this seems unknown territory…
