Two years ago, my Synchrony Walmart and JC Penney cards were sold/transferred and closed. WM went to Cap1, JCP remained at Synchrony. On my credit reports, the Cap1 WM card shows its date of opening as the date the *original* card was opened, some 7 or 8 years ago. But the JCP card shows its date as two years ago--in other words, I lost several years of history. It hurts my scores, albeit very slightly, in two different ways: one, as a 'new' account in the last two years and, two, as only having two years of history instead of the 7 or 8 it should be. The two cards have the exact same 'closed' date.
The WM card has no notation about having been sold/transferred, but the JCP does--and it says 'transferred to another office' (or similar).
When this first happened, I did attempt to get the JCP card's opened date reset to its original date, but had no luck. It's bugged me ever since. When I look at my reports with my cards sorted oldest to newest, and see it at the bottom of the list, when it should be a good deal higher, it makes me mad. Since BOTH cards were at the exact same company, closed on the exact same date, and everything, I just don't get why one retained its original date but the other didn't. Is there anything that can be done at this point to try (again) to have its original date reported?
I am going to "guess" that this would be bank....and therefore Sychrony specific whereas they picked up a portfolio and chose to not keep/honor the original date.
Something tells me they aren't going to be willing to change this for you.

Yeah, I know, my gut tells me the same thing. But what's weird is that the JCP card REMAINED at the same bank! It was before and is now a Synchrony account. As noted earlier, on my reports the old account shows 'transferred to another office,' i.e., the same company, just a different office. That's why it never made sense to me that of the two cards, *IT* is the one that didn't retain its original date!

It remained with the same bank (although a spin-off to SYNCB from GECRB), whereas the Walmart MC went to Capital One. ALL SYNCB upgrades from store versions to V/MC were treated the same way as your JCP MC -- no exceptions, regardless if they stayed with SYNCB. The rules were very simple with the disclosures they provided to you at the time, store account would be closed, MC would report/be created as a new account. I'm sure you may not recall the details (or screenprinted them), but that's how store card upgrades functioned until recently.
That said, within the past week or so, SYNCB appears to have changed their methodology for new V/MC upgrades. So, any upgrades going forward appear to retain the account history.
Thanks @FinStar for your insight and thoughts on this.
While I do recall being notified that they were being transferred/upgraded, I don't remember anything about their terms and conditions, etc. I save *everything* though, so I'm sure I have any e-mails, snail mails, screenshots, etc. I just haven't looked for them.
But based on what you've said, I don't think there's any reason to bother. *I* was looking at it like "it's the SAME bank!! why can't they just reuse its original date?!" and "WM went to a completely DIFFERENT bank, but they're using its original date!! UGH!!"
Oh well. Thanks for the explanations.

Sure, no worries.
Now, potentially (we don't know yet -- although a glimmer of hope), they could revisit how previous accounts that were given an upgrade be treated the same and remain consistent with current reporting standards similar to new store card upgrades. You'll have to see if this happens for you in the future and report back.
In the past, it has happened with other lenders such as Comenity, for example, where previous acquisitions of other lender portfolios were synced up with a single account vs two separate tradelines. One of the reasons that a lot of folks hesitated when presented with any Walmart, Sam's Club, GAP/Old Navy/BR, American Eagle, TJ Maxx, etc., upgrades was the downside of the store card getting closed, no carryover of history, and the V/MC reporting as a new account. So, if someone didn't want to tank their AAoA, was barely on the cusp to clear 5/24 or were in the process of obtaining a mortgage, it was best to hold off.
