DB upgrade

Situation:

In performing the upgrade for MSSQL database from MSSQL 2005 SP4 to MSSQL 2012.

Current ECC system is ECC 6.0 EHP4 SP6/ Kernel 720 Patch 500 Unicode/Windows 2008R2/MSSQL 2005SP4.

Question:

Do we need to update SP stack and kernel to update database to 2012?

Thank you and best regards,

Jie
