Migrate from WPML

At this time, we do not plan to include such feature.
I don’t know how work WPML internally but I think they seperate translations of a same post in different database entries (whilst qTranslate & mqTranslate packs all in the same post).

I think you should have to make a script which packs translation of a same post content and title together. Same for tags, categories, etc.

Do you have a specification for how you store data in mqTranslate?

I will be happy to share my migration script when I am done.

Translations are packed in corresponding fields (for example, post_title) using these syntaxes:

<!--:language_code-->Text comes here<!--:--><!--:other_language_code-->Other text comes here<!--:-->

or:

[:language_code]Text comes here[:other_language_code]Other text comes here

Those two syntaxes can be mixed.

Does it work for attachments and post_meta fields as well?

Attachments: yes
Post meta: not at this time
