Parameters

-Item <Item>

The item to be added to the source. If used in pipeline after e.g. Get-Item the source is created once all items are piped into it.

-Name <String>

Name of the item source.

-SkipVersions <SwitchParameter>

Add this parameter if you want to skip versions of the item from being included in the source and only include the version provided.

-InstallMode <InstallMode>

Specifies what installer should do if the item already exists. Possible values:

• Undefined - User will have to choose one of the below. But they probably don't really know what should be done so not a preferable option.

• Overwrite - All versions of the old item are removed and replaced with all versions of the new item. This option basically replaces the old item with new one.

• Merge - merge with existing item. How the item will be merged is defined with MergeMode parameter

  • Skip - All versions remains unchanged. Other languages remains unchanged. All children remains unchanged.

• SideBySide - all new item will be created.

-MergeMode <MergeMode>

Specifies what installer should do if the item already exists and InstallMode is specified as Merge. Possible values:

• Undefined - User will have to choose one of the below. But they probably don't really know what should be done so not a preferable option.

• Clear - All versions of the old item are removed and replaced with all versions of the new item. This option basically replaces the old item with new one. Other language versions (those which are not in the package) are removed but only for items which are in the package. All child items which are not in the package keep other language versions. All child items which are in the package are changed.

• Append - All versions of the new item are added on top of versions of the previous item. This option allows for further manual merge because all history is preserved, so user can see what was changed. Other languages remains unchanged. All child items which are not in the package keep other language versions. All child items which are in the package are changed.

• Merge - All versions with the same number in both packages are replaced with versions from installed package. All versions which are in the package but not in the target are added. All versions which are not in the package but are in the target remains unchanged. This option also preserves history, however it might overwrite some of the changes. Other languages remains unchanged. All child items which are in the package are changed.
