Please let description of the migration process from Paperclip to ActiveStore?

[Sega100500]

In Paperclip, files are located in specific directories - there are no difficulties with accessing them. But how to convert (transfer) they to ActiveStore storage? So that they are available through the ActiveStore storage via CKEditor.
Let's say CKEditor is already configured to use ActiveStore, there is a separate directory with Paperclip files.
Please describe the script that will allow me to add all these files to ActiveStore, while making them available via ckeditor_assets - and get new links to these files. Further in the text of the pages the Paperclip links can be easily replaced with new links to ActiveStorage files that getted.

Many thanks!

P.S. There are recipes in the Internet for transferring from Papreclip to ActiveStore, but they are all unrelated to the this gem CKEditor, and this is the main task - to connect all this through the gem Ckeditor (and with relation ckeditor_assets).
