Migrate Data from one SAN to other in AlwaysON configuration with no/minimal downtime

Team,

There is a requirement to move the current DBs from existing SAN to new IBM SAN disks. I have outlined the below steps. Request you to please add your inputs/challenges/risks.

This is in Always ON and We have 3 Nodes. 

Server A , Server B and Server C

A and B are Synchronous

C is hosting Async replica.

Note: The SQL binaries are installed on E: drive which is a SAN drive. Whether is this going to be impacted based on my steps below?

1. Present the new SAN of same size  on all the nodes in the Availability Cluster.
2. Break the secondary replica. On Secondary replica, Migrate the data by physically moving the DB files from old SAN to new SAN.
3. Rename the new SANs back to the original filenames as it was present earlier. Bring up the services and join to Availability Group. Check whether the DBs are Synchronized with Primary.
4. Now, Failover the Primary to Secondary replica- This will be a short outage.
5. Follow the same steps on Primary as mentioned in Steps 1-3.
6. Check the Synchronization of the DBs and perform all the sanity checks.

Thanks!
