We're on RHEL 6.5 and CA PM 2.8. CA PM3.1 documentation indicates RHEL support up to 6.8 for DR.
PM 2.8 documentation states DR is supported up to RHEL 6.7.
Community post here indicates Vertica can now run on 6.8 but not sure if applicable for our Vertica on PM 2.8.
Upgrade from 2.8 to 3.0
Can I upgrade to 3.1 on my current OS version RHEL 6.5?
Then OS udpgrade to RHEL6.8 or RHEL6.7 if forced.
Then upgrade from 3.1 to 3.2? I see PM 3.2 says it recommends 6.8, 6.9, & 7.3 but supports 6.6 - 6.9, 7.3)
Perhaps there is another update option but first attempt to wrap my head around it looking at documentation from multiple versions.
