OP here. We don’t specify, but it’s big enough that it’s not reasonable to do a dump and restore style upgrade.

The strategies in the post should work for any size database. The limit becomes more a matter of individual table sizes, since we propose using an incremental approach to synchronizing one table at a time.

I'll take your word for it. Anyway, thanks for sharing the article.
