Brocade 48000 - Firmware Upgrade Question

I'm preparing for a firmware upgrade on our 48000's.   A while back both encountered an out of memory condition (I think) and failed over to the other CP.  The current CP state is:

M48_Switch_2:admin> hashow

Local CP (Slot 6, CP1): Active, Warm Recovered

Remote CP (Slot 5, CP0): Standby, Healthy

HA enabled, Heartbeat Up, HA State synchronized

Can I perform a fabric OS upgrade with the active CP in a "Warm Recovered" state, or does it first  need to be in a "Healthy" state.  If it needs to be Healthy, how do I get it in that state ?

--->>>A while back both encountered an out of memory condition....

this issue must have other reason, output from hashow, show fine.

check if any dump is available and remove, and check errshow for some other details.

Thanks.  I'm not too worried about why the fail-over occurred.  We're at 5.3.2c, and might have encountered a defect that is fixed in  a newer release.    I have all the firmware files downloaded to get up to V6.4.3 (one level at a time) and just want to verify that it's OK to start a firmware update to a CP that's in a "Warm Recovered" state.

yes that is ok.

when you start firmwaredownload command, the procedure perform first the secondary partition on standby CP,  and standby CP show ok.

which FOS release you want to use for first Upgrade from 5.3 to 6.0 ?

Re: Brocade 48000 - Firmware Upgrade Question

Since Brocade recommends only one level at a time under 6.X, my plan was:

5.3.2c (current level)

6.0.0c

6.1.2c

6.2.2f

6.3.2e

6.4.3c

I think that's the highest supported level for a 48000

Thanks !
