Hi, I'm taking a backup of the 3CX v12.5, and I see there are a few things I can chose to ignore. If I don't check the option "Include contents of Firmware Folder", what will happen?? I'm planning to restore the backup on to the v15.5. All the phones we are using will remain the same expect for the obvious client for windows. So, do I have to check "Include contents of Firmware Folder" during backup, or what happens if I don't? Thank you.
