As mentioned you will not get a new tradeline on your reports for the upgrade and your AAOA will remain the same.
Welcome to the forums.
Usually product changes or product upgrades will keep the credit history. There are certain exceptions to this rule but I don’t believe those apply to this situation.
What are the exceptions based on? The respective individual or company? Assuming the later, but I'm looking at a PC on two 20 year old accounts so obviously don't want to learn the exceptions the hard way
Product change will look like closing old account and opening new account on credit report.
Correct; most lenders will keep the entire history and either nothing at all will change with the reporting or the "new" card will just replace your existing one retaining all of its history. Never a bad idea to ask here about particular lenders, though. CapOne I can confirm that nothing at all changes in regard to product changes.
Good to know. What about BofA and Chase? Do they maintain AAOA or reset?
@K-in Boston just looking at another thread where you said that co-branded Chase cannot be PC into Chase Freedome etc. Combining your feedback from these threads leads to a...
Nuanced question, can you PC a United Chase to another United Chase? eg - legacy product into say, United Explorer or Club Card?
without AAoA reset?
edit: I see you already replied here, but I also saw your reply in the other thread (linked here if anyone stumbles across this some day)
Bank of America and Chase both retain all account information with a product change.
Yes, you should be able to change between any of the 9 personal United credit cards, and there would be no change in the account age.
