Hello,
Please see my replies to your questions below:
1- Related to Unified interface:
- When was/will the release date of the stable production version of (Unified interface) for MSCRM on-premises?
We are working on a major On-Premise Upgrade, currently scheduled for the last quarter (Q4) of 2020, however, there’s no official confirmation on the fixes and features that are going to be included on it.
- What is the road map to upgrade (from legacy to Unified interface) if available for our mentioned version? Or we must upgrade this version to another version to get the unified interface feature?
On your version (9.0.2.3034) it’s already available the Unified Interface, however, you cannot define it has default since it’s not fully implemented yet.
- When the support will not be available for our version legacy forms?
On online environments it’s supposed to end the support in October of 2020, however in On Premise environments we don’t have plans to deprecate this soon.
- When the support will not be available for unified interface for on-premises too?
We don’t intend to deprecate this interface soon so we will continue providing support.
2- Related to SDK:
- While using our current version of SDK does it use internally SOAP or web API?
By default, the version 9 of SDK it’s supposed to work with web API, however, you can keep using SOAP, since we don’t have plans to deprecate it.
- Should we upgrade to a newer version of SDK?
Updating to the newer versions of SDK is always recommended both for the new added features as well as fixes that are rolled out.
- When the support will stop of SOAP in the on-premises or our version of MSCRM?
We don’t have a time frame where we would take it completely down, however we would like to advise that If your going to use the SOAP endpoint, please make sure your using the oAuth auth flows to support it. If your using .net , you can use the CrmSvcClient with an appId to cover that for you, if your using non .net, you can likely find the auth lib you need on AAD’s Git Hub page..
Please let me know if you have any more questions.
Best Regards.
