How to migrate WordPress posts with photos?

Question

WordPress

Good afternoon!
Need to migrate 7,000 posts to WordPress. The transfer occurs via CSV from Bitrix. The articles have photos, with a direct address. For example, site.com/upload/iblock/973/973bdec21e4c7bce5c26f76... I tried this: I launched a WordPress site locally, transferred 7000 posts
using the Really Simple CSV Importer plugin. Then I made an export in WordPress format (Tools - Export).
I launched the second WordPress site locally, using the WordPress Importer plugin, I imported the posts (checked the box next to “Download and import file attachments” ). Only 2000 entries were transferred, not a single photo was uploaded to the media files.
Questions:

1. Why does the default WordPress export transfer a maximum of 2000 posts? Is it possible to increase this value somehow?
   
2. Is it possible to somehow upload photos to media files, with changing links to them in posts? (The manual method is not suitable here, there are many entries)
   

Answer 1

The problem was solved with the Media Tools plugin .
