Hi,

This looks good... except I never did an export/import for unicode conversion, so, I cannot help you on this timing part.

Are you using downtime-minimized strategy? if so, the prepare phase can be done a few days before go-live.

in my case, the real downtime for the upgrade took about 6 hours.

Hi all,

We test upgrade from SAP 4.7 to ECC6 + UNICODE conversion + installation EHP4
can someone let me know if the following durations are normal?
1/ Upgrade 4.7 to ECC6 (9 hours), + preparation phase (2,5 hours) + Unicode conversion (export (10,5 hours)/ import (16 hours)) + post processing (2 hours) : Total timing = 45 hours
2/ EHP4 installation: duration 40 hours

Hardware and DB information:
OS: 2003 server 64 bits
12 GB RAM
4 processors Xeon Intel dual core 2.3 GH
Oracle DB 10.2.0.4
DB size: 288 GB

Regards
