Our standard build is to install binaries on C drive & Instance Root directory in f:\SQLSERVER during SQL 2008R2 install.
I have found a server that does not fit the 'standard build' the default instance root directory is D - I know I can change the default for database locations after the install, but I actually want to relocate everything on D to F - with the introduction of the 'Instance ID ' in SQL 2008 is this easy to do i.e. follow standard system database & user database relocation instructions or is there something else I need to consider in regards to the 'Instance ID' and registry keys .
My preference is to rebuild and restore user database - but the customer does not want any extended down time .
Any suggestions would be appreciated.
