dns - Connect to SQL Server Default Instance From Named Instance -
i doing side side upgrade 2k8 2k12. original machine named instance , new machine default instance. goal not change connection strings applications.
if going default instance default instance change dns record , have connect. however, application storing connection string oldserver\oldinstance. record going change oldserver name connection still looking \oldinstance.
can sql server 2012 configured have default instance accept connections when made instance not exist?
thanks, chris
i went through exact process few weeks ago, , found out sadly not appear possible without uninstalling old instance (which wanted nothing with). here of many links found on subject , imagine have been through well.
i tried number of different things on local , not 1 of them worked me. in case, if have upgraded server (downtime have happened) have done it, going sql 2k8 enterprise sql 2k12 standard not possible either.
i interested in seeing if comes way can done outside of uninstall, not come 1 , read seemed up. maybe someday sp_dropserver/sp_addserver change instance names.
