As I already said, you must first have your custom modules working properly on the target version (with tests) before thinking about upgrading the data.
yes I would do that if there would be tests available.
Do not blame us, blame the author of those modules.
I donât blame anyone, sry if this was badly communicated. I appreciate the work you do and the help that I receive via this forum.
Its definitely on my list to write some tests once I get a better understanding of tryton and the modules we use at work, so it will be easier to update our modules.
Actually I think itâs not too much missing for us to have a working tryton5.0 with our database. The problem with the missing invoices seems to be an empty table of the database. To me it seems like the invoices were not copied into the dumpâŠ
The upgrade process is not copying anything, it alters the database in-place.
