Hello Everyone
I have SQL Server 2008 engine installed on two nodes with MS-Cluster. The whole system installed on hyper-v environment and the operating system is Windows Server 2008 R2 64-bit Standard.
The system works fine without any issue and the cluster working just fine.
Now, I want to upgrade the SQL server to 2014 standard edition and I have few hours to shut down the DB servers. So, I need to setup an upgrade plan and work according it. I need your help with that plan.
I suggest to do the upgrade by implementing the following steps:
1- Take Full backup of all DB attached to the SQL server.
2- Install windows server 2008 R2 SP1 on both servers (as a requirement of SQL Server 2014).
3- Turn off the SQL services on both nodes.
4- Upgrade Node 1 SQL server 2008 Standard to SQL Server 2014 Standard.
5- Upgrade Node 2 SQL server 2008 Standard to SQL Server 2014 Standard.
6- Run SQL services.
7- On node 1, test the system.
8- Move SQL services to node 2 from MS-Cluster
9- On node 2, test the system.
Notes:
-------
1- The current license of SQL Server 2008 is for 4-Cores x 2 (VM) servers (Total 8 Core)
2- The new license of SQL Server 2014 is for 2-Core x 2 (VM) servers (Total 4 Core). No changes will be made on the VM no. of Core (remain 4 core per server) the change will be on the SQL license ONLY.
