We have a server running CENTOS 5. But we must migrate to version 6, to use multiple SSL on a single ip.

We have two options:

1) Do a full backup and then do an upgrade on Linux and pray that everything works.

2) Up a new machine, install cpanel, configure, migrate the accounts and then change the ips. For the new machine is with the current IP.

I need opinion about what is best to be done?

If the second option is better, I have some questions:

a) The cpanel settings can be migrated? Save a backup and restore all settings on the new server?

b) How is the license? Only have to change the ips and run that command the license? (/usr/local/cpanel/cpkeyclt)

Please inform tips, opinions, solutions ... If there is any way to use multiple SSL certificates on a single IP without having to migrate the Linux kernel would be even better.

Tks

Hello :)

Ideally, you should consider configuring a new server with CentOS 6.x and then migrating your accounts over to it using the cPanel transfer tools. Directly upgrading from CentOS 5 to CentOS 6 is a major upgrade. While it's likely possible to complete with cPanel installed, it's not recommended due to the potential configuration errors that could arise. The following post should help you get started:

Transfer Configurations to new server

Note that licenses are IP-based, so provided the source server IP is licensed, it will continue to be licensed on the new server.

Thank you.

People, came another question.

I was backing up these files:
/etc/wwwacct.conf
/var/cpanel/cpanel.config

However, in the /etc folder, these files have drawn attention:
cpbackup.conf
cpbackup-exclude.conf
cpbackup-userskip.conf
exim.conf (I created the whm)
named.conf
pure-ftpd.conf
quota.conf
tcsd.conf
updatedb.conf
warnquota.conf

These other files should be ignored? I've stayed hours configuring the current server, I would not have to carry it all over again.

Hello :)

There's really no need to transfer any of those files other than the ones starting with "cpbackup" if you utilize backups on your system. Other than that, you can copy over "pure-ftpd.conf" if you have custom Pure-FTP configuration changes. You can backup Exim settings via "WHM Home » Service Configuration » Exim Configuration Manager"

Thank you.
