I would like to know how it's possible to do the migration.
I have sql 2012 express installed on my server and the only way I find to migrate to 2019 cu14 is to do it with 2 step :
2012 -> 2019
2019 -> 2019 cu14
The 2019cu14 installation file doesn't work to upgrade from 2012.
How is it possible to do the migration in 1 step ?
