We have a very old SAN box with about 6 TBs.
There are 2 ESX v4 Hosts attached to it.
Our Windows infrastructure is based on Windows 2008 R2 OS.
We are planning to replace this SAN box and we would like to know if there is any way to do side by side migration.
Create another SAN box (brand new one) and migrate VM one at a time to minimize the downtime and risk.
Any best practices or procedures are appreciated.
