We are currently using Microsoft Dynamics NAV 2015. The application and database server is on-premise.
We want to migrate the database server to Azure(so that its more stable and ease of management).
Can we just migrate the database server? without the application server? and change the credentials of the NAV instance?
Does it work that way?
When you move your NAV database, then you also move everything in it, data and the objects you may have customized. So when you run the client (web or windows), then NAV uses those objects to show your data etc.
You can migrate to Azure in many different ways. The most simple way is to try it with http://aka.ms/getnav - that will setup a virtual machine (VM), with NAV and SQL in a container. Fully accessible remote, so that you can still use your clients as normal on-premise. This setup is really only for test/demo or very low number of users.
Normally you would have the NAV server on one VM and SQL Server on a different VM.
If you have a large database and lots of users, then using Azure SQL is also an option.
But no matter which option, then when you have studied this a little more, you should contact a NAV partner with Azure experience (which now a days should be most of them). They can help guide you and set it up so that it matches what you need in your company.
