Dear forum,
The title is slightly misleading, I know Apex is running within Oracle, so I can't move it out completely.
So the next best option would be to use an Oracle XE database with Apex, and only move 99% of our data to MS SQL.
We're thinking about Restfull services to read the minimum of data into Oracle XE.
Any other tips would be welcome.
The reason:
Over the years we built a nice application in Apex we don't want to loose.
But due to the license-policies from Oracle (with databases running in clusters) it becomes unsustainable to keep all data in Oracle.
I hear from quite a lot of companies that Oracle is being pushed out. It's unfortunate, I did like PL/SQL and Apex but as Oracle seems to be keen to kill it's customerbase, we'll have to find a work-around.
