Hi,

We are planning to move our CRM implementation to cloud(SAAS).As CRM system cant be standalone system,it has various integrations with different systems which are consuming CRM data.Rest of the systems are staying on-prem,does anyone know what network and firewall changes needs to be done on prem systems so a security wont be compromised.

    Hi Rahul,

    I am not sure which datacenter you are in, but there is a list of ip address ranges that are consumed by dynamics 365.

    You can look at the following post to see the list of whitelisted ip addresses for Dynamics CE:

    support.microsoft.com/.../microsoft-dynamics-crm-online-ip-address-ranges

    You can download the list from here:

    www.microsoft.com/.../details.aspx

    You would have to add those settings to your firewall...

    Hope this helps.

    Thanks a lot Aric,it was useful.What about the other way around if we have to access on prem webservices from cloud CRM?

    As long as you whitelist these ip addresses, CRM will be able to access the resources from your local environment.

    For example if you need CRM to access the Exchange Server Api/Web Service. If the IP address of CRM is whitelisted on your firewall, it should be able to access the Web Service of your Exchange Service.

    Are you looking for something else?

    Thanks Eric,we are consuming WCF services from CRM.Just last thing what changes we have to do for authentication so it would be secure.Right now we are using BasicHTTPBinding.If you could provide some sample links that would be much appreciated.Thanks in advance.

    For the migration itself, wouldn't it be faster using a 3rd party tool? Have a look at this article https://www.connecting-software.com/blog/how-to-sync-on-prem-database-to-dynamics-365-online/

    And once you are done with the migration, if one of the systems that is included in your various integrations is SharePoint, then please be aware there is a security issue with the permissions https://www.connecting-software.com/blog/microsoft-dynamics-365-privileges-sharepoint-permissions-replicator/
