I have an Ambari 2.1.2, HDP 2.3.2 installation on SLES 11 SP3. We wish to upgrade them to Ambari 126.96.36.199 and HDP 2.5.3. Due to some other software dependencies. We would also be doing a OS upgrade to SLES 12. HDP 2.3.2 doesn't have SLES 12 support (OS being more recent than the HDP version). What would be an ideal way of doing this ? How different are the packages built for SLES 11 and SLES 12 ?
HDP 2.3.2 -> HDP 2.5.3 with SLES 11.
Upgrade OS to SLES 12.
Do we need to redeploy bits packaged for SLES 12 post this ?
