Clarifying vanilla WP / WPMS migration steps and language

Re: WordPress Multisite

Priority: Medium

Issue Description:

This section about how vanilla WP / WPMS migrations happen on Pantheon is overly vague and has caused some confusion for customers with lesser WPMS experience.

Specifically, the sentence starts out by talking about how existing vanilla WP sites "cannot be converted" to WPMS, which seems to imply the vanilla WP site is on Pantheon already since this limitation doesn't apply to most other hosting providers. The latter part of the sentence goes on to say that "they", seemingly referring to vanilla WP sites on Pantheon, "can be migrated." And there is a link to documentation that explains how to migrate a non-Pantheon WPMS to Pantheon.

This sentence lacks continuity in the topic it is covering, because the secondary portion is discussing non-Pantheon WPMS and how to migrate it to Pantheon. That is a different scenario than the beginning portion of the sentence that is implicitly referring to vanilla WP sites on Pantheon.

Suggested Resolution

Expand the highlighted content to be more inclusive of relevant scenarios and starting host environments. In my opinion, we should cover at least the following scenarios.

• non-Pantheon vanilla WP -> Pantheon WPMS
• non-Pantheon WPMS -> Pantheon WPMS
• Pantheon vanilla WP -> Pantheon WPMS
