Hello, I can confirm that everything works now.
I give an additional warning that surely will be useful for all; beware that scheduled tasks in the previous tommy2 environment are still active if you leave them enabled, and I guess that during this upgrade phase, filesystems of both instance are shared between them.
I have some tiny scripts that write some data in csv files, today i find out that records were doubled in some case, and file was a lot littler in size than expected; it turned out that there were written by the same task in both tommy2 and new tommy istance! So I login in old tommy2 istance and disabled the scheduled tasks.
