Router category_id update

[WM 7Ebra]

Version:NodeBB v3.7.1
DataBase: MongoDB 7
Theme:Harmony
Tryed: Search "Category" on Doc and Community;Try to find related plugins

Like:

Before:
/category/1/A
/category/2/B

Then delete category B and add new one
/category/1/A
/category/2/B

After:
/category/1/A
/category/3/C

I want to:
/category/1/A
/category/2/C

Q:
Can I update the category's sequential id's so they are in order, do I have to update the database, or is there any documentation link reference? Thank you!

@WM-7Ebra There are quite a few internal references that use the cid, so it's not quite that simple to dive into the db and change things (though please don't let me stop you )

If you don't have a lot of content on your forum, it might just be easiest to trash the forum and start over!

Or if cid 2 is still around (not purged), you can delete all of the topics inside it, and move all the topics from cid 3 into cid 2.
