ERP 6.0 EHP 4 upgrade- How long to choose to wait before entering downtime?

48 Views

Wondering if anyone has relevant downtime minimized experiences to share on how long an ERP 6.0 EHP4 production system upgrade can/should wait to confirm phase DOWNCONF_TRANS (at end of the upgrade Preprocessing roadmap) before choosing to enter actual downtime?

We are on our final production system upgrading a simple ERP 2004 only landscape to ERP 6.0 EHP 4 (NW 7.01) running on the IBM i 6.1 platform and could be ready to wait at DOWNCONF_TRANS for actual downtime to start for up to two weeks to meet non-technical business needs. As the IBM i platform doesn't support Incremental Table Conversion (ICNV) it doesn't seem any harm to get this preparation work done early and wait until the optimal business downtime opportunity to enter downtime...

Anyone have actual experience (or a SAP recommendation) on a "well resourced, moderate load" IBM i production system waiting a week or more before starting downtime as above?

Thanks in advance for relevant responses :>
