I have some entries that I'd like to move to a different channel, but I don't see any way to do this. Is it possible?
It’s currently only possible via direct manipulation of the entries in your database.
You will first need to visit your
sections table to determine the desired section ID, and then the
entrytypes table to determine the desired entry type ID.
Once you have those, find your entry’s row in the
entries table, and change its
typeId columns accordingly.
NOTE: If either of the the old/new sections are Structures, there’s quite a bit more work involved, and your best bet will be to write some PHP code to handle the migration. See https://craftcms.stackexchange.com/a/4467/9 for a complete example of how to do that.
