I have read extensively regarding the process of introducing a new hardware NW6 server into my small NW4.11 environment. DS on 4.11 is at 6.21, SP9, etc. After ensuring the health of the DS, I will extend the schemas on both 4.11 servers with NWdeploy. Will the 4.11 servers be happy running with this extended schema for any amount of time? I would like to let them run for at least a few days before installing a new server so as to ensure nothing is awry.
