Vertica 7.2.3 data files can be used with Vertica 8.0.1 ?
I have a Vertica 7.2.3 cluster running on Red Hat Enterprise Linux Server release 6.5.
The Vertica data files directory is in a specific filesystem.
I plan to upgrade my platform in term of OS version and Vertica version:
I plan to scratch RHEL6.5 and install RHEL 7.3 on all the nodes;
and also plan to uninstall Vertica 7.2.3 and install Vertica 8.0.1.
The question is:
Since my Vertica data files directory is in a specific filesystem that will not be touched by the RHEL upgrade, could I use Vertica 8.0.1 with my data kept in this filesystem ?
(I might have to keep vertica catalog somewhere also)
