If you are upgrading from v1.5.0 you need to do another DB migration. This
|
||||||
|
should not take long. For optimal database performance after the migration it is
|
||||||
|
recommended to apply the new `optimize-db` flag, which runs the sqlite `ANALYZE`
|
||||||
|
and `VACUUM` commands. Depending on your database size (more then 40GB) the
|
||||||
|
`VACUUM` may take up to 2h.
