Importing outside chat history: ofMessageArchive vs ofMucConversationLog?

I have about 95000 messages from another chat system I’m looking to import into Openfire 3.8.2.

Schema seems simple enough. But I’m a little confused about these two tables.

ofMessageArchive is used by the Monitoring plugin, which implements the Archive and Search XEPs, so I’m fairly certain I should definitely import the messages here.

But should I also import the messages into ofMucConversationLog? What functionality do I get out of this, how is the data in this table exposed differently?

It is not really possible to rebuild the exact conversation structure for these old messages. So if I just use admin’s “Search Archive” and possibly plan to build a plugin for my own special view or AJAX interface, it looks as if I should simply focus everything on ofMessageArchive?
