Hi,
OK, so I looked at https://www.virtualmin.com/documentation/system/migrate and read a number of threads that seem to say that document may be incomplete or the tools might be short, although some of those threads seem quite dated.
So, just looking for a sanity check:
I have a virtualmin/cloudmin/webmin system. Platform is CentOS 6.6 (Final). I want to upgrade it to Centos 7. My question is, would this procedure work (for me a couple of hours of downtime is alright, we have hard outage maintenance windows):
- Follow the instructions from above link, dumping the backups to a spare hard drive.
- Power off system
- Install new hard drives (for ease of rollback, drives are pretty cheap comparatively)
- Power up system
- Install new Centos 7 using minimal install ISO, configure with same primary IPV4 and IPV6 addresses as old system
- Install webmin/virtualmin/cloudmin with automated installer script
- Restore backups from spare hard drive
8 Have all servers up with same IPs and settings from Centos 6.6 system on new Centos 7 system?
It seems like it should, however some previous posts seem to indicate it might not be quite that simple?
Thanks in advance,
