UCS firmware from 3.2(2f) to 3.2(3I) or 4.0(4e)?

I am planning an upgrade of my environment - I have 2 domains each consisting of 3 5108 chassis, 6248 FI's, B200 M3 and M4 blades, and one UCS Managed C220-M4S. Currently at 3.2(2f) all running ESXi 6.0 U3. vSphere has been upgraded to 6.7 and I want to upgrade the blades to 6.7 as well and figured I could do both OS and firmware upgrades at the same time for each blade once the UCS infrastructure is upgraded. My question is are there recommendations around which track to upgrade to? 3.2(3I) and 4.0(4e) are both new and both the "starred" versions. 

Any advantage / disadvantage to staying in the 3.2 track? Or any advantage / disadvantage going to the 4.0 track? It looks like both are compatible.

Any thoughts / advice would be appreciated.

Thank you.

Hi ,

Have a look at the below links and then decide which version to upgrade.

Thanks. I had already looked at all those things before posting my question, and both versions were compatible which is why I asked the question to begin with. I decided to stay on the 3.2 track for now and upgraded to 3.2(3l) successfully.

Go to 4.0 as this is the latest. UCS doesn’t have any long lived releases. The patch point is the final Major Release in a code train and End of Sale/Support gets announced on the Major Release. You wouldn't want to stick with 3.2 and then have to do a step upgrade to something greater than 4.0, unless you have a specific need to stay at 3.2.

Yes, go with 4.0 or higher.  Once you start to purchase M5 blades you will need 4.0x or higher.
