EHP4 to EHP6 upgrade on MAXDB

    Hi All,

    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.

    Regards

      Hi Ratnajit / sunny,

       

      As we discussed both EHP4 and EHP5 is not supported for 7.9 but its an upgrade, SAP agreed for an support on 7.9 with EHP4 / EHP5 ( But inconistency may come on CCMS). Hence as a prerequisite complete testing has to be done on test system.  This what SAP replied via OSS message.

       

      In that case, below will be the sequence

       

      1. DB upgrade from 7.6 to 7.9 on the current landscape which is EHP4 / SP8 for Basis

      2. OS upgrade from RHEL5 to RHEL6

      3. Using SUM will updgrade from EHP4 to EHP6 directly. ( Because the prerequisites will be met with respect to OS / DB )

       

      I believe this will be the sequence

       

      Note : We are not planning for system copy here ( Could combine OS / DB upgrade together as one downtime ) but we planned and opt to go for the above sequence – considering other factors

       

      Indeed, we are doing DB upgrade activities as first activity because for RHEL6 prerequisite for MAXDB is 7.7.
