Bank Account opening date

Hello All
I am preapiring my ILR application Set(M)-SPouse. I am filling the online application, and it is asking for all my previous passports that I used to enter the UK. I changed the passport once, and don't have the old one. Luckily, I always scan passports before renewing so I have a scan. I can upload. However, will they ask for the original previous passports at the biometric interview as well?

will they ask for the original previous passports at the biometric interview as well?

No. Also, it is not an "interview".

I am going to rely on cash savings to qualify financially. My savings have been scattered around different banks, so I decided to open a new account back in November 2023, and I am now slowly moving cash into it. In the form, it asks about the bank name and account number and when it was opened. My savings now are 50/50 split between an account opened 5 years ago, and this new account.

Does the opening date have any significance on the approval? I will make sure the minimum funds required have been there for a minimum of 6 months.

It should not have any effect
