Overview of Upgrade and Merge Options
The Upgrade/Merge Wizard includes the following options for upgrading and
merging DAC repositories:
Repository Upgrade (DAC 784)
Use this option to upgrade a DAC Repository in the release 7.8.4 format, which
has a non-partitioned DAC Repository structure, to the new release, which has a
partitioned DAC Repository structure. For more information, see "About the
Repository Upgrade (DAC 784) Option".
Use this option to upgrade the DAC Repository when you are upgrading from an
older release of Oracle BI Applications to a new release. For more information, see
"About the Refresh Base Option".
Simplified Refresh From Base
This option is similar to the Refresh Base option.
It allows you to upgrade the DAC Repository from an older release of Oracle BI Applications to a new release
without comparing repositories and creating a Difference Report. For more
information, see "About the Simplified Refresh From Base Option".
Use this option to upgrade the DAC Repository when you are phasing out an
older release of a transactional application and moving to a newer release, for
example, phasing out Siebel 7.5.3 and moving to Siebel 7.8. For more information,
see "About the Replace Base Option".
Peer to Peer Merge
Use this option to merge DAC repositories of different instances of the same
release. For example, in a development environment you may have two instances
of a DAC Repository used with Oracle BI Applications release 7.9.5 that you want
to merge. For more information see, "About the Peer to Peer Merge Option".
