Can you be a bit more clear on what it is you're asking? It sounds like you're talking about Bungie.net accounts, but you're saying Destiny 1 and Destiny 2 accounts as if they're different IDs on your PS4, which makes it seem like you may be talking about two different PSN IDs attached to two different Bungie.net profiles. So, as I don't fully understand your question, I'll answer you as generally as I can in hopes that one of my replies will answer the question you're trying to ask. If I don't answer your question, please do rephrase your question to make it a bit easier to help you out. Each profile can only link 1 of each platform account to it. If you used a different PSN ID for Destiny 1 than you used in Destiny 2, then you simply need to unlink the wrong PSN ID from the Bungie.net profile you're wanting to link to and then link the other PSN ID to it. If, instead, you mean you cannot see your Destiny 1 characters on Bungie.net, that's because Bungie.net no longer supports viewing and tinkering with Destiny 1 characters. If you have the same PSN ID on both Destiny 1 and Destiny 2, then only your Destiny 2 characters will show up on the website. If, instead of all of that, you mean you have an older Bungie.net profile that you orphaned by mislinking an account, you can recover it if it's been within the last 90 days. If it's been more than 90 days, then your old Bungie.net account is now archived and no longer available to recover.
