I dont get very well.
You created 2 pixels (one for personal ad acc and another another for business manager)?
You can move the personal ad acc to business manager and I think you will have the same pixel.
If you created an ad campaign on the personal ad acc and used the BM pixel, there's nothing you can do. Just change the pixel ID or create a new campaign on BM using the already warmed pixel.
I'm not sure if I answered to your inquiry because your post is pretty confusing
This are my understanding of the AD accounts and business manager.
Personal Ad Account - An ad account created from your "personal profile" in which you develop you personal brand. Ex: My name is Joe Shoe, I have a personal Facebook account I use for socializing, but I also want to build a personal brand and career through making a Facebook Business Page. When I make that page under my personal identity, this is my "Personal Ad" Account.
Ad Account- These are created off of pages that I create, for brands or other businesses I wish to start. I make an Ad account to correlate with each Business Page I create, assigning one Ad Account to each Business Page to advertise for that page (with likes)
Business Manager (Consult Case) - A way to manage my "Personal Ad Account" which pertains to my personal brand correlating to my identity, "Ad Accounts" which correlate to my individual business pages connected to my "Personal Account" (not personal Ad account, but the original Facebook page with friends), and to manager clients "Ad Accounts" which correlate to the pages that represent the businesses that they own.
Currently, the pixel I installed and that has been collecting data from my website has been created under my Business Manager names (Consult Case). There is a drop down menu in the Events Manager, this is the option that says (Business Only), and has a brief case next to it
. I have attached a picture for clarification. I need this pixel to be on the new Ad Account I have created, since I just discovered that you can only run Ads from an AD account and I would like to use the data my pixel has already collected to run conversion campaigns on my AD account.
