Hello, I want to upgrade a multiple server ISPConfig environment (1 CP, 2 Mail, 2 DNS, 2 mySQL and several Apache servers) from 3.0 to 3.1. In the past, the upgrade "lost" the DKIM patch. Are there any issues that I should be aware of before upgrading ISPconfig? Also, I am a little confused on when to reply 'Yes' or 'No' to the upgrade questions like "Reconfigure", etc. Any comments or suggestions are appreciated. Thank you.
