Can I switch to the 65k monthly transfer rule for my Thai Non-O retirement visa, or do I have to maintain the 800k rule until my next extension?

I have been on non o retirement extension for 11 years with no problems.

I have used the 800k/400k rule for every extension to date.

My visa is due for extension again in April 2023.

I still have sufficient bank funds to cover requirements for visa extension

but

I would like to switch to the minimum 65k monthly transfer/deposit rule. I have been transferring 65k plus every month since January this year (2022).

My question is: do i still need to abide by the 800/400 rule until April 2023 when my new extension is required or do i just need to show proof of the 12 months plus minimum 65k monthly transfer/deposits to qualify for my next 12 month extension ?

Or do the two need to run in tandum up until my next extension renewal ?

Would be great to hear from members who have already went through this process or anyone who is aware of the process.

Thank You

James
