sqlite3 migration to MySQL or Postgress

[preussal]

Do you have instructions on how to migrate the SQLight Database to MySQL or Postgress?

I have now the problem with ~ 60 mirrors that I keep getting “sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) database is locked”

only a restart of all 3 service help to resolve this for a short time

Thank you, Installation - Check Create DB - Check

Migration need also install sqlite3 apt-get install sqlite3

Migration Dump export

root@gitlab:/home/gitlab-tools # sqlite3 gitlab-tools.db .schema > schema.sql
root@gitlab:/home/gitlab-tools # sqlite3 gitlab-tools.db .dump > dump.sql
root@gitlab:/home/gitlab-tools # grep -vx -f schema.sql dump.sql > data.sql

Check

But the import Fails

I think i need to Cleanup the Dump This Lines to a lot of truble INSERT INTO celery_taskmeta VALUES(4207,'e777290c-d716-4492-93ae-f99bf8d0a3a0','FAILURE',X'80059581.........

I found the mistake, both in the SQLITE3 DB and in the Postresql. My name contains a "ß" (German Special ä ö ü ß) and in the db dump from gitlab-tools it is something like the "a/o = n" and that somehow breaks.

ERROR:  syntax error at or near "user"
LINE 1: INSERT INTO user VALUES('2024-02-05 12:42:41','2024-02-05 12...

I changed my name and now the SQLITE3 DB is going again :)

Yes dump will most likely need some manual cleanup (some commands may not be supported etc)
