G-Speed Drives from Studio XL to Shuttle XL

Our G-Speed Studio XL Thunderbolt 2 48TB controller [chasis] has failed. The drives are all OK.
Since the warranty is over we cannot get it repaired or replaced.
We are looking into ways to access our highly priceless media and files.
Our system is directly connected to a 2013 Mac Pro with Thunderbolt 2 cable.
Is it possible to buy the new G-Speed Shuttle XL [with Thunderbolt 3] and insert our old drives [configured in RAID5] into the new chasis and gain access to all our old files?
Does anyone have any real experience with this?
Any information might help us. Thank you all.
