I don't know if this is the right place, but...
I have test installation of IAS 3.14.xx on Windows 2016. I wanna migrate it to Centos 7 and then upgrade it to 3.21
Migration using DMT goes well (need to run it 3 times in order to migrate all users and digipass), but upgrade on Centos or IAS upgrade.sh is giving me headaches.
Upgrade to 3.15 goes smoothly, server is not in migration mode, stared ok after upgrade all well.
Then I want to update to 3.16 but, this is what I get after starting ./upgrade.sh
