Errors after transfer to a new server

Our hosting company have transferred us to the new server, and now when we try to look at any unread threads, we get this error:

XF\Db\Exception: MySQL query error [1364]: Field 'thread_read_id' doesn't have a default value in src/XF/Db/AbstractStatement.php at line 230

What could be a cause? What to ask them to check for?

It's solved by manually transferring DB again. After that, it started working.

It's closed.
