c# - New suite of service wrapping earlier endpoints -

we have 10 web api service endpoints. no creating suite of wrapped service endpoint these endpoints, iterative step categorize/segment earlier set of services in respective product areas without breaking underlying functionality.

for example: post http://example.com/product

would become

post http://example.com/internal/v3.5/masterproduct/product (while call endpoint http://example.com/product)

what kind of caveats should approach aware of can take necessary cautionary steps?
