how to use the new paths in existing filesystems in Windows

Hi,

We have facing an issue with the ESX  performance issues on FA 7A/10A, so moved the rest of wintel servers from that Director to 04D/13D

Now we want to unmask the old paths of 7A/10A on these windows servers.

Actually windows admin has to scan the new paths in disk management/VEA & make sure new paths are visible in powerpath. Later do they need to update the filesystems with the new paths or powerpath will take care ?

Please suggest, we want to do this activity without any interruption.

Thanks  in advance !!
