Hello Shreeram,
Maharashtra CET state cell has scrapped the SAAR Portal. They are coming with the new process. So you don't have to worry regarding submitting these many documents as of now.
If you have already registered on SAAR and paid fees, there is nothing to be worried as they will be refunding the money.
Once the new registration process opens you will have to register there and continue. This process will be as per the older processes and you need not worry about the documents as fewer documents will be required. As you are from the open category, very fewer documents will be required such as domicile, nationality, etc.
Please keep checking this website https://admission1cet2019.mahacet.org.in/cet2019/mba19/
Hope this is helpful.
