RE: CRM upgrade from 2011 to 2016
Hi,
(Assuming you are already aware of CRM 2011 needs to upgrade to 2013 -->2015-->2016 )
I am not sure which options you are using for upgrade. Either Side By Side or In-Place Upgrade.
Reference - (community.dynamics.com/.../microsoft-dynamics-crm-upgrade-from-crm-2011-to-crm-2013)
MSDN: technet.microsoft.com/.../hh699673.aspx
1. Side by Side ( New CRM App Server and New SQL Instance - Recommended ) :
- You will need to re-import all the Organizations and during import you will be asked to map the CRM User's with AD.
- The Existing Solutions will be upgraded. If you have any vendor solutions , you may need to check with them for any unsupported or patches required along the upgrade.
- New Solutions you need to make sure they are supported/compatible with you each upgrade versions.
2. In-Place Upgrade ( Existing Environment - Risky ):
- No Re-Import of Organizations. No require to map Users in AD
- The Existing Solutions will be upgraded. If you have any vendor solutions , you may need to check with them for any unsupported or patches required along the upgrade.
- New Solutions you need to make sure there are supported/compatible with you each upgrade versions.
Suggestion: Have rigorous checklist to make sure you are testing you organization after each version upgrade and definitely your custom code for any unsupported endpoints.
