Hi,

What are the steps for moving a CA from a Windows server 2008 to a Windows Server 2012 R2?

And what kind of problem could we experience afterwards?

All of our computer, laptops etc. are using this CA.

You can use below guide for CA migration from 2008 to 2012 R2
The guide is upto 2012 at this moment, but i believe that it will applicable to 2012 R2 as well

http://technet.microsoft.com/en-us/library/ee126140(v=ws.10).aspx

I am just outline high level steps here

backup 2008 CA certificate with database and its registry
uninstall CA server role from 2008
Shutdown server for time being
prepare 2012 R2 member server with same host as old CA server
Install CA role with existing certificate (from Certificate backup taken above) on 2012 R2 server
Restore CA Database backup taken above from CA console on 2012 R2 server
Check if CRL and AIA entries in active directory sites and services are appropriate as your source and destination CA server Hostname is same.

Note:Do not change CA server Hostname otherwise your existing issued certificates will not able to check CRL
Once you are sure that new CA is working as expected, you can use old 2008 machine for else purpose with different host name.
Because if you face any issues on new CA, you can just uninstall CA from new server, rename it to some new name, start your old CA server, install CA role and just restore CA backup and you will be back in business.
Also you cannot change CA common name in AD
