Changing from Elasticsearch 7.10.2 OSS to Basic version

Hi, I'm currently using Elasticsearch version 7.10. OSS version but when trying to implement security ran into challenges which turns out is because I am not on the basic version of Elasticsearch. Is there a way I can change my type from OSS to basic?

I don't think this is possible.

The best approach would be to make a snapshot of your data, install a new cluster on version 7.17 since version 7.10 is not supported anymore and then restore the snapshot.

Thanks for the advice. On version 7.17 can i add security and authentication? (
