Hello,
I am wanting to accomplish a couple different server migration tasks and am wondering if I could get any advice on the following plan.
1) I want to clone my current SmarterMail server version 12.3 which is a VM and move it to a different data center/IP range. I will have both the old and new server running concurrently.
2) On the new server, I want to upgrade from 12.3 to the latest version 14 so there will not be any down time and affect customers on the old server.
3) Once upgraded, I will copy over the each domain's folder from the old to the new server and update the DNS records for that domain at that time.
My concern is will there be any problems with the licensing when running two servers on two different IP's while we are performing the migration of domains from one server to the other? I am not sure how long this process will take as some customers manage their own DNS and they can sometimes be difficult to coordinate with.
Secondly, are there any issues copying older version 12 domains to the new server which has probably gone thru and converted the file formats to the new version 14 for these same domains?
Thanks in advance for any advice or potential pitfalls I might run into.
Best regards,
Eric
