Upgrade tool to be used
It would be great if you can clear a confusion.
I would be upgrading R/3 4.7 to ECC 6.0 EHP 5. As per EHP 5 upgrade guide and note 1863907 (note suggests that SAPup needs to be used for release upgrade and SUM for updating or upgrading EHP levels) the tool that should be used is SAPup. However I read that SUM can be used to upgrade R/3 4.7 to ECC 6.0 EHP 6.
Please throw light on my below doubts –
– Is SUM tool only used when EHP 6 comes into picture (like updating or upgrading to EHP 6)?
– Can SUM tool not be used to upgrade R/3 4.7 to ECC 6.0 EHP5 or any update or upgrade to EHP 5?
