[TYPO3-english] Re: Data Transfer from Other CMS into Typo3 CMS

[Naberd Zendi]

i think your best bet is to look at https://docs.typo3.org/typo3cms/extensions/external_import/
or write custom script to insert queries in to database.
pages
pages_language_overlay
sys_file
tt_content
if you can fit your database export in to this tables then you have  migrated all your data. except for users.

unless you have restricted pages to specific groups and users this shouldn't be that difficult.
