I have already started with the export-import from .com to .org.
I get following error when trying to import attachments:
Fatal error: Out of memory (allocated 30408704) (tried to allocate 1240999 bytes) in /homepages/16/d337807910/htdocs/asuapedefin/wp/wp-includes/class-http.php on line 1105
By the way, not all pages, comments, entries... have been imported. Shall I try by pieces (I mean, I export all entries, and then all pages... or by date)
