Sharepoint 2010 Upgrade Question - A customer is currently running sharepoint 2007 on a 64bit windows 2003 OS with SQL 2005 sp2, they are looking to install/upgrade to Sharepoint 2010 and want to use the current SQL server,for the upgrade a new SharePoint
2010 environment will be built and for a short while they will have two instances of SharePoint running SP2007 and SP2010. The plan is to then manually migrate the data from SP2007 to SP2010 (ENT), the web and application servers will be newly built. From
research I think they have three options
1) Upgrade the current SQL 2005(SP2) instance to SQL 2008 R2 standard.
2) Install a new instance of SQL 2008 R2 on the same server and have both SQL 2005 & SQL 2008 running on the same server (Is this an option? Will sharepoint happily run from a SQL server running two SQL instances, do I have to be
careful regarding the installation and configuration, could I break the existing sharepoint farm doing this?)
3) Upgrade the current SQL server to SP3 and install a new instance of SQL 2005 SP3 and install SharePoint 2010 Enterprise here, again I have all the questions from point 2 above.
We are thinking of trying option 1, then 2, then 3, and obviously only moving to the next option if we come across a show stopper. H
