I was curious if anyone knew if the following config is supported.
Our 'main' filer has a volume that we make available in remote offices using flexcache. All of our filers are still running 7-Mode and we are about to do a forklift upgrade of our main filer.
It is tempting to go to Clustered OnTap but its not clear if I would also have to upgrade all the filers in remote offices to Clustered OnTap at the same time as well or if I can continue to use 7-Mode and still be able to access the volume on the main filer via flexcache.
Thanks
