I've taken the liberty of aiding in the category renaming effort by creating Template:Migrate category to, Template:Migrate category from and Category:Obsolete categories. The templates add notices to category pages in the process of migration from one to the other, while the obsolete categories category gathers known categories still in the process of migration so as to show what work still needs to be done. The idea is, the old category's description and parent categories can be migrated over first, but still contain the notice that it is being migrated to another category, and still contain all the article and subcategory entries that have not yet been migrated. When the migration process for a category is complete, the notices can be removed and the old empty category deleted.
