My existing production fileserver VM is running out of disk space, the specs are as follows:
Windows Server 2008 R2 Standard SP1
8 GB vRAM
C:\ 50 GB
D:\ 1.9 TB – Data 1 disk space is 97% full
E:\ 1.85 TB – Data 1 disk space is 95% full
Note: Both D & E drive are shared by the network UNC path to different department and then mapped using the GPO login script.
I’d like to upgrade it to Windows Server 2012 R2 Std. to compress and dedupe it to reduce disk space used because I cannot extend the VMware disk anymore.
Is there any caveats or things to consider when performing the inline OS upgrade from 2008 R2 to 2012 R2 as Windows VM ?
Once it is converted to 2012 R2, can I perform the Data Deduplication straight away without impacting the user data access during business hours ?
Any caveats and tips would be greatly appreciated.
Unfortunately due to the limitation of the VMFS datastore, I cannot clone the whole VM with D & E drive.
Both D & E drive are NAS shared (running on HP EVA 6400 not RDM).
Do I need to double the specs of the VM to prevent slowness issue during upgrade or data dedupe ?
