While migrating my Orchard 1.9.1 project to Orchard 1.7, We have used the Arana.VersionManager from Orchard gallery.
We further customized it to our needs and had used the Restore method of Orchard.ContentManagement.IContentManager in 1.9.1
ContentItem Restore(ContentItem contentItem, VersionOptions options);
However, when we went back to Orchard 1.7, there is NO Restore method now. I really don't want to lose this Restore functionality. Please suggest next steps. Where is the CODE of this Restore method of Content Manager in 1.9.1 ? Can simply including the code in 1.7 will work ?
