At present our DB servers and applications is running on 32-bit environment.
We are planing to migrate DB servers from 32-bit to 64-bit on fail over cluster.
But as all the servers are in live we can't stop users from accessing the solution.
So we need to install 64-bit on one server and then migrate all the applications to that server
and then Install 64-bit on another server and bring them to cluster and should be same as 32-bit environment.
Please suggest me the best way to proceed further.
