Hi Geoff, thank you for your article. I'm trying to enable pool HA but ending up with the following error message:
The restore could not be performed because this backup has been created by a different (incompatible) product version I have ACS 4.4.1-NONOSS_3 with XS 6.2 patched up to XS62ESP1013 installed. I see 2 files were created under MGMT-HA mount, but HA is still not enabled. Could you please let me know what might be wrong?
