we currently have an instance of Dynamics CRM 2011 underpinned with a SQL Server 2008 R2 database.
The extended support end dates for the different components are as follows:
Platform End of Extended Support
SQL Server 2008 R2 July 2019
SQL Server 2012 SP1 July 2015 (SP1 end of support)
CRM 2011 July 2021
I’m now struggling to see what we can do (if we need to do anything) to remain supported.
I can see no benefit for us to upgrade from SQL 2008 R2 to SQL 2012 SP1 as this went out of support before SQL 2008 R2 (CRM compatibility information I have been able to find states that CRM 2011 is compatible with SQL Server 2012 up to SP1 and not beyond. SP1 support end date is July 2015).
My question now is can I assume that as CRM 2011 is supported until July 2021, any compatible SQL instance used will also be supported by default and the individual SQL end of support date is ignored?
If this is not the case, what options do we have?
The best option is to upgrade both your Dynamics CRM instance and your Microsoft SQL Server database to newer versions. Ideally you will upgrade to Dynamics 365 for Customer Engagement (on-premises) and Microsoft SQL Server 2016, or Dynamics 365 for Customer Engagement (online).
Microsoft Dynamics CRM 2011 is supported until July 2021, but this does not mean that any compatible SQL instance used is also supported by default and that the individual SQL end of support date is ignored. Keep in mind that Microsoft Dynamics CRM 2011 has an online version that retains extended support until its expiry date two years after Microsoft SQL Server 2008 expires in July. Mainstream support for Microsoft Dynamics CRM 2011 has already expired.
Your SQL Server will not be supported even if CRM is still supported. If you need support and the underlying issue is related to SQL Server 2008 R2, you will not be supported.
As previous recommendations, I would start considering an upgrade to a new version of Dynamics 365.
