compatibility between postgres/GIS is a little tricky.
This is a good starting point to see what you have to aim for.
Next challenge is to figure out a workable upgrade path as it is not unlikely you will have to go through some intermediate steps.
Maybe it would help whether you can specify which PostGIS version you are coming from on the source (postgres-12) Installation.

And it seems like posigis extension I have on V12 is not compatible with V15.
