Thank you, Joe. I will upgrade the operating system in January. Will I have to do a new install of Virtualadmin then?
When I try to log in now this is what I get:
Error - Access denied for 73.206.91.60. The host has been blocked because of too many authentication failures.
Not sure where that IP address is coming from. Can you please look into it and let me know what is wrong?
Thank you on the ticket update.

That is the IP you're connecting from. (Or, at least, it's the IP Webmin thinks you're coming from.) ;-)
Webmin has brute force protection.
The block will be removed after a while (I'm not sure how long it is, but it's probably only a few minutes for the first occurrence). I was able to login from my IP. I checked the current block list, and there are no hosts on it (including that IP), so you should be able to login now.
Upgrading the OS in place would not require a Virtualmin reinstall, but it would need a couple of configuration changes. But, I don't think there is a good way to upgrade CentOS 5 to 7 in place; I think they finally have in-place upgrades via yum/dnf arriving in the next CentOS release, but, as far as I know, all of the current versions are not easily upgrade-able in place, and they recommend a fresh install. So, for that, you'd need to backup your domains (and I would also recommend performing a full system backup, just in case anything else needs to be pulled back onto the new system), install the new OS fresh, and then restore your domains.

I can now log in. Thank you very much. I am worried about the fresh install as our data is so very important to us. I'll do everything I can to backup everything. Thank you for the tips.
Happy Holidays to you and yours!

If you can't move to a new server (while keeping the old server running as a "just in case something goes wrong" measure) you could do a test install and restore on a spare machine, just to be sure all of the data makes it across. It wouldn't need to be a powerful machine, or even a server...it could be a virtual machine on your desktop or laptop machine. You just need to know that once restored, it'll all work and all of your data will be there. You've got some time to test it thoroughly, so take advantage of it.
Since it's just for testing purposes, you wouldn't need another Virtualmin license, and you wouldn't need it to be fast or powerful. So, grab VirtualBox, setup a VM with CentOS 7, install Virtualmin, and practice backing up and restoring your sites. And, we'll be able to help if any issues pop up...and we're best able to help if it's not a problem already in production but only on a development system!
