I upgraded to latest and lost everything

I upgraded docker manager from my default site. After upgrade I got the message to do launcher rebuild app. Which I did. I got message in there that post gres is updated run rebuild again. Which I did. But my default site is working as expected but the second site lost everything. It is not a fresh instance. But it got only one system post welcome.

What I did is changed postgres_data to postgres_data_brocken and data_old to postgres_data and tried rebuilding it again got same response for postgres upgrade from 15 to 18 and to rebuild app. But with same results. Please help

sudo du -sh shared/standalone/postgres_data_old
678M    shared/standalone/postgres_data_old

❯ sudo du -sh shared/standalone/postgres_data_brocken   
412M    shared/standalone/postgres_data
_brocken

I think something is messing up when db for second site is migrating.

make sure you have enough disk space, you need roughly double db size. Sorry nothing to add or help but see this thread for clues:

Yes I have checked it out but nothing for multisite upgrade
