If you're moving from one machine to another then you will need to reinstall all your applications then identify and copy over all of the data that they require. There is no easy "magic button" way to do that other than hard work and experimentation.
CentOS 6 will die in November 2020 - migrate sooner rather than later!

CentOS 5 is dead, do not use it.

If you can keep the old machine and you use LVM (default option) , then you can use pvmove to migrate all your data without downtime.
