How to Move Multiple WordPress Subdomain Blogs to a Single WordPress 3 Multi Site Blog
You must enable the Multi Site features of your WordPress site before proceeding beyond here. Read this JournalXtra guide to learn how.
This guide is split into 4 parts:
- Exporting Your Subdirectory Blog
- Importing your old blog into your new blog
- Mirroring Settings
- Deleting the Real DNS Record
Each part contains a step-by-step guide to effecting its title. If you get stuck, either google for an answer or ask a question in the comments. Better still, do both. I will answer all questions within 24 hours (except Saturdays, I don’t work Saturdays).
Getting rid of multiple WordPress installations in favor of one Multi Site installation can be a good idea for those who want to save a bit of space and who need to have easy access to their sites’ admin pages with a one-time login to only one of the sites within the Network. It probably isn’t a good idea if the sites to be transfered have a lot of custom files included within them; and it can take a painfully long time to transfer a site when the site being moved is large.
The general method of transferring your subdomain site to your Multi Site subdomain site is easy. Complications only arise when plugins, themes and included files are incompatible with WordPress 3 MS so check compatibility first.
For the benefit of non-English speakers, here are two important definitions:
- Export: to send out.
- Import: to bring in; to put in.
Export is the opposite of import. In relation to this article, to export means “to copy or backup a WordPress blog” and to import means “to load the content of one blog (the exported one) into another blog”.
That said, follow this guide to export a single subdomain blog installation into a Multi Site blog installation; or, put another way, follow this guide to learn how to import an old WordPress blog into a new Multi Site blog.
