More than likely the firmware of the new unit will be v6.x.x. If you're wanting to do asynch replication do the following. The best way to accomplish the migration without downtime would be to add the new PS6100 to the management group (and storage pool) the PS500E is in and allow the volumes to spread across both members.  Next delete the PS5000E from the group (under the Group - Members tab) and the system will automatically evacuate remaining data to the PS6100.  Once that has finished the PS5000E is ready to be reconfigured (the existing configuration will be wiped out as part of the deletion) in a new group, and set as the replication partner. The only thing you'd need to do on the VMware side in this scenario would be to add the second group to you iSCSI initiator (on the dynamic discovery tab) so that it's ready if you ever need to connect to a replicated volume. If you're wanting to do synch rep do the following. The best way to accomplish the migration without downtime would be to add the new PS6100 to the management group (and storage pool) the PS500E is in and allow the volumes to spread across both members.  Next create a new storage pool and move the PS5000E to it, all remaining data will be evacuated to the PS6100.
We currently running VMware ESXi and have a PS5000E in production with firmware 5.2.4 and have purchased a PS6100 to replace it (current firmware unknown). We want to use the 5000 in the future as a replication partner. What is the best method to move all the data over to the new SAN and remove the old SAN and not incur any downtime? And is there anything that has to be done on the VMware side?
