I have migrated a J3 to 4 site and installed advancedmodulemanager-v9.0.3-pro.zip.
There was a lot to migrate on this large Joomla site but with respect to AMM, the assignments correctly migrated to conditions, however, in some cases, the matching method switched from ALL to ANY and one case that I have seen so far. As well, the URL condition was properly selected, but the URLs one would type in the the URL field did not migrate over and was blank. As you can imagine there are many modules to review but i odes seem in general that the assignment migration did not go smoothly.
Do you have a backup of the old (J3) database?
If so, could you send me the backup of the xxx_modules and xxx_advancedmodules tables. And preferably just the modules that did not migrate completely ok?
I do have the old tables because this is a trial migration on localhost. I will have to migrate again to see things in the broken state because I have already fixed some of the incorrectly migrated settings.
