Was anybody successful in migrating fedora to CentOS? If you are, can you provide the detailed instructions, commands etc.

Please explain what you mean by "migrating" -- those are two different, although similar, distributions.

You'd have to install CentOS, then copy (from your backup) /home and other user files. You may be able to also copy some configuration files, as for email or the web server, with various degrees of success.

So we're running fedora servers, most of them are fedora 24 and few are fedora 20. The task is to move all these servers to CentOS, simply we wanna get rid of Fedora and move to CentOS. What's the first thing to start off with?

I would suggest backing up data, then a clean install of CentOS and restore of data. Since these are completely different platforms, there probably isn't a clean path to switch from to to another, like an "upgrade".

Define your exact requirements, what applications you need, what service you are going to provision, you give no indication if these are desktop machines or servers.
Create a CentOS machine, install the applications and services you identified at 1.
Test, Test, Test, Test.
Create a migration plan and inform users.
Create a roll-back plan just incase things don't go to plan
Execute #4, re-do #3 and hope you don't need #5

santhosh94, just so you know why the other guys are saying you need to do a clean install; it's because while Fedora and CentOS are both Red Hat distributions, Fedora is a "bleeding edge" distro, CentOS is basically the free version of Red Hat Linux itself. CentOS is therefore not even close to a "bleeding edge" distro, and just like Red Hat Linux itself, is very conservative about which software is included with CentOS, and which software isn't.
