Most CLARiiON arrays can be upgraded from FLARE release 14 directly to release 24 or 26 without any interim steps.
For instance, a CX500 could go from FLARE 14, 16, 17 or 19 directly to FLARE 24 or 26 without any issue. There are some caveats depending on the array model and whether or not it contains any ATA shelves, etc. But for the most part, there really isn’t any extra time involved.
Of course, the CX200, CX400 and CX600 can only support up to FLARE 19. If you’re still running one of these older arrays, you’re probably paying too much for maintenance and missing out on all the new bells & whistles. Bite the bullet and purchase a fancy new CX3!]]>
