Migrating from latest ghost-4 image to ghost-5

[pirat8]

Hi,

I use currently ghost-4 in latest version but only with the integrated sqlite database. I have in my docker-compose file only the ghost-service and no database service. I want to upgrade to ghost-5 image. However mysql8 database seems mandatory now. So I have to introduce mysql8 as a new service.
Question: What is the recommended upgrade step-by-step process? Can I just update the ghost-image to ghost-5 an additionally add the mysql8 service and the migration from sqlite to mysql8 is done in a magic way?! Or is it more complicated?

Best regards
Thomas
