Selectively Update is a very powerful tool for reconciling differences, but please use caution when using this tool because you can introduce errors into your schema.
When a comparison is performed with Selectively Update, the results of the comparison are presented in a Tree view, allowing you to choose which differences to resolve. This Tree view can contain nodes New Objects, Modified Objects, and Deleted Objects depending on the results of the comparison.
-
The New Objects node, when expanded, identifies all the objects that exist in the compared with file (or configuration) that don’t exist in the opened file (or configuration).
-
The Modified Objects node, when expanded, identifies all the objects that exist in both files (or configurations) but have at least property that has different values.
-
The Deleted Objects node identifies all the objects that exist in the opened file (or configuration) that don’t exist in the compared with file (or configuration).
Selecting nodes from this tree control and then selecting OK will result in the changes for the selected nodes being made to the opened file (or configuration). Therefore, selecting all the nodes in this tree control and then selecting OK will result in the opened file being made to be the same as the compared with file.
By selectively choosing which modifications to apply, you can control which changes are actually made to the opened file (or configuration). Therefore, you can choose to take some subset of the differences and apply them to the opened file.
Using Selectively Update improperly can introduce errors into the opened file. Therefore, you should be careful
for any case where you select a subset of the full set of differences to be applied.
The file (or configuration) should be validated after this command has been executed
and any new problems that are found by validation should be resolved before proceeding
further.
