What do you mean 'it didn't work'?  You couldn't mount the new partition, or
your system mounted it but didn't work right?

I'm confused as to what you're trying to do, but here's what I think you want
to do:
 Boot the live cd, and mount the original / and the new /var partitions.
 mv /oldroot/var/* /newvar/
 edit /oldroot/etc/fstab to add entry for newvar
 touch /oldroot/.autorelabel

You really don't want to try to migrate /var over while the system is on-line.
 You might be able to get away with migrating while in single user mode.

The last step should fix selinux before anything could fail because of it.
There's a way you could do it while booted in the liveCD (involving chroot and
restorecon), but it's easier (but more time-consuming w.r.t. system downtime)
to just relabel everything.

HTH,
