Question about elqTrackID in URLs

I’m currently migrating various individual emails (which are in many languages) to dynamic content. Thankfully, these were created using the HTML editor, so it’s a fairly simple (if not tedious) process of copying & pasting the body of the email into the dynamic content editor.

My one concern is regarding the URLs: when pasting the HTML into the dynamic content editor, it’s including the elqTrackID from the original email. If I delete the elqTrackID from the link in the Dynamic Content and hit Save, it generates a brand new one.

Will leaving the elqTrackID query string from the original email cause a problem with reporting, or should I scrub all of the links of their original elqTrackIDs?

All help is appreciated!
