>Upgrading from Domino 8.5.1 with Traveler to 8.5.2 with traveler no problem
and it takes no time.
1. I copied the installation files to the server 3 files
Domino HF for SMTP
2. Shutdown the domino services
3. Started installation files for Domino
4. Started installation file for Hotfix
5. Started installation for Traveler
6. Started domino services again
Total time of upgrade max 15 minutes, bet that Microsoft if you can!!!
Of course we need to upgrade mailboxes but that can be done later no need for that
And there might be some other problems with your server but this server was straight forward no problem 😉
