How to approach upgrading from OData3 to OData4

0
Within our application landscape we have 5 applications using OData to communicate with each other. Some OData services already use OData4 and have been using this since we created them, others are still using OData3. To make everything future proof and as efficient as can be we want to "upgrade" everything to OData 4. I know OData3 uses XML and OData4 uses JSON, but I wonder if we need to make any changes in our Mendix apps other than just "slipping the switch" to OData4. Our BI team uses our OData services, so they would probably have to change up some things in the way they process our messages going from XML to JSON. I'm just worried upgrading might not be as easy, and I'm missing a few steps. On the other hand I'm worried I'm overthinking this, since I haven't come across similar questions on the forum or documentation on how to approach this. Any tips and tricks are greatly appreciated!

Hello Manon,

 

It seems to me that it is indeed just the switch you describe when i read the documentation:

 

https://docs.mendix.com/refguide/published-odata-services/ 

 

But what you always can do is to try it out with a branch line and a test or local environment to see the results for your self.

 

Hope this helps,

 

Good luck!
