I have a small-ish MDS environment, with only about a dozen CMAs, with fairly small policies in each. I want to upgrade to R80.10 mgmt, and have a spare Smart1. From everyone's experiences so far, what of the below options would be the better approach?
1. Manual move - Since there're not too many CMAs and polices are small, it wouldn't be too terribly time consuming to recreate all this manually. It would also allow the opportunity to clean things up a bit as they are moved. What sounds the most negative with this option to me, would be re-configuring all the gateway blade settings manually.
2. Gradual upgrade using export/import - Seems easy and automated, but there's the trust factor with a script doing things for you. And I'm not clear on how it works with having two different MDS' with different IPs, and migrated CMA with new IP, regarding SIC and licensing, etc, etc
3. All in one shot migration - Same risks with scripting as gradual, but seems the IP and licensing issues go away with this option.
4. In place upgrade - Similar to #3, but likely faster?
