Hi,
first of all I would like to thank you for this system 
This solution is really cool and save our time!
We have Leantime instance installed from Turnkey Linux and w have some troubles regarding that.
After successful upgrade v2.3.27 by internal script, I can’t upgrade Leantime anymore. After few errors, web don’t show up, and I don’t have access to data base. Apart from this, the system in version 27 works stably with minor errors.
I recovered the system from snapshot so nothing happened but I want to keep Leantime up to date.
And after this too long introduction, a question: Is it possible to migrate DB from normal installation to docker-compose installation and keep Leantime up to date?
