IS it possible to run two hmail servers for same domain name in same netwok

Post by generaloptics » 2019-02-06 15:12

At present we are using hmail server 5.3.3 with MYSQL in Windows 2008 server.

we are planning to move hmail server to Windows 2016 server and hence we are planning to install latest version of hmail server with MYSQL and move data from old server to new server.

If we install hmailserver in new server and configure the same domain name in new server which are connected in the same network, then i suspect that it will disturb the present setup.

i request experts to clarify my doubt.

Not really. Domains are recognised only by where dns points to. Sam's that involves the routing of the port traffic.

You can safely create the new machine and restore from old machine a backup to the new machine. Only when you point mail traffic to your new machine (at router or replacing the ip address of that of the old machine) will the traffic be directed to it.

Note: you should upgrade old machine to latest before transferring the data to new server OR install the old 5.3.3 on the new server before testing the old version data (and then update to latest version).

You should consider using Windows Server 2019 instead of Windows Server 2016

General availability for Windows Server 2016: October 12, 2016; 2 years ag / End of Support: 1/12/2027
General availability for Windows Server 2019: October 02, 2018; 4 months ago / End of Support: 1/9/2029

You also should check our Database Support EOL-Info:
viewtopic.php?f=21&t=33506

ps: Regarding MySQL. If you plan to use MySQL 5.2x Line, you should need to know Support for this Database ends
in 2023. MySQL 8.x will be supported until 2026. If you want to use MySQL 8.x with hMailServer 5.6 or higher you need to configure
MySQL 8.x in Legacy Authenticationmode, see our Developer Info: viewtopic.php?f=10&t=33531

Hint: If you Install MySQL 8.x without the mentioned legacy settings, the required libmysql.dll 5.x cannot connect to MySQL 8.x (while
other tools like MySQL Workbench can connect.
