Thanks Johnny for the prompt reply. Cleared most of our questions.
We had successfully installed the 64-bits Dirsync and are ready to running the configuration wizard.
Currently, we had stop any admin activity on our local AD (e.g. account creation, change of properties,delete, etc) so as preventing existing Dirsync machine from updating records to Office365.
Before we run the configuration wizard on the 64-bits Dirsync machine, do we need to do anything on our existing 32-bits Dirsyc machine? Or we can configure the 64-bits Dirsync machine to sync to office365, while the existing 32-bits Dirsyc machine is still running?
Assume, if the 64-bits Dirsync machine is successfully configured and able to sync to office365.
The old 32-bits Dirsyc machine, we can just un-install it Dirsync client?
Thanks
KM
