Upgrade and Merge Options

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".

Refresh Base

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".

Replace Base

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".
