Hello Experts,

I currently have two clients that are looking to migrate their PKI infrastructure to Windows 2012 R2 PKI

Client number one has a 3 tier PKI infrastructure[Offline root, 1 enterprise subordinate, 2 cert issues servers]. Windows 2003 is the OS in all servers, and domain/forest functional level is Windows 2003.

Client number two has a 3 tier PKI infrastructure[Offline root, 1 enterprise subordinate, 2 cert issues servers]. Windows 2008 is the OS in all servers, and domain/forest functional level is Windows 2008.

Can someone please provide high-level steps to migrate the entire infrastructure, considering the tier 3 and the OS on each client?

Can someone please provide a check list doc or spreadsheet to migrate PKI servers to latest OS?

Any blogs with tons of screenshots with all steps required by each phase?

We are doing migration, not consolidating.
your client are on the 3 tier PKI structure so this is the microsoft recommended solution.


it is on microsoft support migration path way (from 2003/2008 to 2012)

there are tons of information in the technet i quoted below that include all the checklist and steps for all the required activities.

Please have a read on this article and any subsequence articles.

this is the high level steps you need.
Unless you have hit with a rock, all the plan will looks very similar, until you hit with some issues.
then post another question so we can look into it. If not, i am currently at a planning session but without knowing the environment well.

we can wait for another few days to get other experts, they might have prepared one before, but usually my reference to technet is suffice.
