Review of ACS assessment for new occupation code

Hello All -
Anyone from the forum with experience of requesting for review of the assessment from ACS? I got a positive assessment for Software Tester (261314) on Feb 1st but this occupation is in VIC state list only for now. I recently realized that ICT Systems Test Engineer (263213) in ACT and SA state occupation lists. Both these occupation codes have same job descriptions (100% same, not even a single word difference) and technology and educations requirements. So, I emailed to ACS about this and how I can handle this situation to be eligible to apply for SA/ACT. They have replied back to me saying that I can send 'Review' application and mention the reason as change of occupation code.

Good news is that, ACS folks mentioned in FAQ's and in a reply to my email that both assessment will still be valid and won't cancel/overturn previous application. And Obviously, I need to use only one for last step immigration process, 176/175.

2S) If I Review, will this cancel or overturn my previous application?
No, both assessment will still be valid.

Any advise or suggestion about this with your knowledge or experience and if its a right thing to do? I will just use 263213 for SA/ACT sponsorship purpose, in the worstcase, if VIC state closes 261314 by the time I get a IELTS score with 7 band.

Any suggestions will be very much helpful in going forward in my immigration process. Thanks in advance to all!

Regards,
Sri
