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.

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
