EMC VNX5300 Swap RAID Group Disks between Enclosures

I am in a process of upgrading an EMC VNX5300. Have a RAID Group in DAE0_0 and the DAE is fully occupied with disks of this RAID Group plus Vault drives.

I just wonder if it is possible to add a new DAE and swap disks of mentioned RAID Group to the new DAE and Add up some HDDs and expand it later on?

I know this way we gotto ask for a down time. But we could have down-time for few hours.

You really need to run this by EMC.   Firmware and the specifics of the configuration matter as well.  I can see the answer being either yes or no.

Checking with EMC and it will be riskier than adding the DAE as you intend with the additional drives and then shift the LUN to the new DAE will be a much more straight forward and less risky proposition.
This way your down town will not involve hair pulling if the import of the old drive on the new DAE runs into issues while at the same time the addition of the DAE to the ...........
If not mistaken, you might need downtime to add the new DAE into the SAN.
IMHO, do one thing at a time.
attach the new DAE,burn the disks in.

Do you have support contract in effect with EMC or the vendor through whom the SAN was purchased??

Here is the SPEC for your device

DAE with 25x2.5" drives or DAE with 15x3.5" drives.

You cannot move disks on a live VNX5300 without loss of data. End of discussion. That functionality was introduced in the next generation of arrays, the VNX5200, 5400 5600 etc.

Arnold's suggestion that you install the new DAE then use LUN migration to move data around is your only option, I'm afraid.
