Any rule of thumb migration rates for VMAX VLUN VP migrations

Are there any rule of thumb migration rates for VMAX VLUN VP migrations on a VMAX 20K.

Planning migrations from a 300GB 15K FC pool to a 600GB 15k FC pool and have ~14 TB to migrate in total.

Don't try and run too many migrations at once. Look at your DA utilization before and during the migrations to make sure you are not adding too much load on the backend of the array. I would start with one volume and add migration sessions slowly, monitoring the impact on the backend.

Agree with AranH, just dont over shoot your DAs. If its adding too much to your DAs utilization then you can use QOS to slow down the migration rate.
