EHP4 to EHP6 upgrade on MAXDB
I am working on the preparation for the upgrade for one of our customer. I have done the enough research with upgrade / master guides and also the PAM. But I would like to get confirmation / suggestions from you people about my understanding
Current landscape : RHEL5 X86_64 , MAXDB as 7.6 / SP for BASIS 701 SP8 / EHP4 – Unicode
Planned Landscape : EHP6
Hence I understood from PAM / SUM upgrade guide that for EHP6
Prerequisites from OS and DB are : RHEL6 and MAXDB 7.9 ( Need to meet this prerequisites before initiating the EHP6 upgrade )
But the bad part is for EHP4, it supports RHEL6 and MAXDB version as 7.8 and it will not support 7.9 – So, I am in a position not to start the EHP6 upgrade immediately. Because we cannot meet the prerequisite for EHP6 upgrade (i.e Current Landscape wont support 7.9 MAXDB version)
In this case, Do I need to go for the interim upgrade ( Like going to EHP 5 and then to EHP 6). Will this be the only possible I guess – based on the guides / PAM.
So the sequence has to be
Upgrading : OS to the level from RHEL5 to RHEL 6 and DB ugprade from 7.6 to 7.8 ( May be we could combine together by doing export / Import – If we are doing an hardware migration – Considering my case, The DB size is high and hence the system copy it would be not an option, instead we planned to go for in place upgrade ) –> So, first OS will be ugpraded and then DB will be upgraded
Upgrading : EHP4 to EHP5 ( To the latest level ) — > But wondering even EHP5 is not supporting 7.9 MAXDB ( According to PAM) .. So do i need to go to EHP5 or rather I go to EHP6 ugprade directly.
Wondering how this could be possible or My understading is wrong with respect to the supported version
In addition to the guides + PAM, the notes which I referred are : 817463 , 1142632.
