Hi ASK,
It is a SAP ECC EHP upgrade from 3 to 7.
OS is Windows 2012 R2 and DB is MSSQL2012.
Hardware is HP blade but the production VMs are clustered (MSCS).
Two clustered VMs for SAP ASCS and two other clustered VMs for MSSQL2012.
CPU is 28 vCPU (14 core) on all four VMs, memory is 128GB on all four VMs....
I doubt it is a hardware resource constraint issue but currently there is no way out of this long running TABIM_UPG step. At different test runs, it can go down from just 3hrs. on the bad run, it can go up to 35hrs....
Are you able to share what you experienced previously?
