Author: Alan Cooper. Hi. Just purchased an upgrade from 7.4.16 (64-bit) to v10 64-bit mainly to get TLS 1.2. As this is a big jump in versions is there any potential issue I should be aware of or precautions I should take? Note: I don't use the TB Backup/Restore as I have drive image daily backups using Macrium Reflect. Also my executables are on the F: drive and my data on the H: drive. Also I have 11 email accounts (all pop3) and I have circa 26,000 email messages over 100s of folders...
