Converting saved Analysis for OLAP workspaces to Webi

Hi all,
As you may have heard, Analysis for OLAP is sunsetting soon- so we are looking to convert our several thousand saved OLAP workspaces into Webi documents.

Can anyone recommend ways to do this? Any third party tools available?
Is it possible to build this automation with Java SDK / REST API? If so, how does one go about it? Was unable to locate relevant API endpoints or methods to get OLAP workspace metadata.

Your ideas are much appreciated! Thanks!
