This download is for Umbraco 7.x. There is a separate download below for the older version for Umbraco 6.
This packages adds a menu item to compare a local item with one from another instance of Umbraco. Both sites must be running this plugin for it to work.
Note that items are compared buy Guid in most cases, and Name/Alias in others. This means that creating a node with the same name in both instances won't necessarily cause them to be related and thus comparable. To ensure all items can be compared properly Umbraco Courier or some similar process needs to be used to that local and remote items retain their Guid's.
Also note that this isn't compatible with 1.0 version of the plugin and the two version's won't see each other.
This will allow you to compare the following.
Stylesheets, Templates, Partial Views, Scripts, Media Types, Document Types
Macros, Scripting Files, Partial View Macros, Config Files(Config Tree plugin), Data Types
You need to set CompareItemsRemoteUrl in your Web.config's appSettings section to another umbraco instance that also has this package installed.
