I would like to migrate / update my CRM version 4.0 on premise to Dynamic 365 on premise.
I have found a few articles updating CRM version 4.0 to CRM 2011, and even more articles updating CRM 2011 to Dynamics DRM 365.
Is it advised to go through all the CRM upgrades to get to Dynamic 365?
CRM 4.0 -> CRM 2011-> CRM 2013 SP1 -> CRM 2015 -> 2016 -> D365
Is there a faster, better way to migrate / update to Dynamic 365 on premise from CRM version 4.0?
You basically have two options when it comes to old versions like 4.0.
A: Follow the upgrade path just as you describe, upgrade one version at a time and adjust customizations accordingly.
B: Recreate your CRM configuration and customizations in D365 and then migrate all data.
Option A is pretty straightforward and you won't have to deal with data migration and mappings but there's a lot of overhead work if your solution is pretty small.
Option B is great if you have a small solution with few customizations and not so much data but becomes a pretty big project if you are running a heavily customized installation.
In both cases, you will need to rewrite custom code to match new standards and oversee any third party extension you are depending on since those often are no longer available.
Agree with Daniel,
For option A, in fact, we need to follow all migration path due to differences across the product versions.
If you pick up the option B, you could use custom third app or tailored SDK apps to consume data from CRM 4.0 and move to newest version.
