Copy TM backups from shared TM volume to new HD

I am using a Drobo Gen2 as a TM backup drive. I have three Macs that backup to this drive. The volume was shared as a TM backup drive. The Drobo will not work in Catalina and above so I want to reuse the drive pack in an external Raid enclosure. I want to copy the current backups to a new volume however

I can only 'see' the backups for the attached Mac. The backups for the other two Macs are not accessible.

Any ideas on how to transfer all these backups to a new HD?

OS10.14.6

iMac 27″, macOS 11.0

Following a false start, I used SuperDuper to copy all files to a temp HD. 3TB and 5 days later files had been copied. Assigned the temp HD as the TM drive. Opened TM and…. [drum roll]… all backups were viewable from all three devices and backup worked successfully.

Now deciding whether to use a OS SW Raid 1solution or two TM drives. Leaning towards the latter.

Good call, BDAqua.

p.s. Drobo support were useless…. "No Longer Supported"!
