DLB and Mapping Rules
●Keep same input/output for each flow to
avoid regression problems
●The external system must update the host but
not the endpoints
GET https://NewHost/v1/contatti
GET /v1/contatti GET /v1/contacts
Runtime 3.9
On-premises
Runtime 4.4
In-Cloud
GET https://OldHost/v1/contatti
NB.
The endpoints with URI params cannot be mapped correctly
/v1/contatti/{id} à /v1/contacts/{id} –KO
/v1/contatti à /v1/contacts –OK
The method cannot be mapped by DLB
POST/v1/contatti/{id}/search à GET/v1/contacts/{id} –KO
