While migrating from SQL server 2000 databases to SQL server 2012 databases , we need to follow one of the below approach .
SQL server 2000>>SQL Server 2005 SP4 >> SQL server 2012
• Clean approach to migrate Remediation of Non ANSI SQL 2000 code to ANSI complained code
• TOC of SQL server 2005 is less than the TOC for SQL server 2008
• Amount of remediation for data type deprecation, syntax changes is high from SQL 2000 to SQL 2008 migration
SQL server 2000>>SQL Server 2008 R2 >> SQL server 2012
• Remediation for SQL 2000 and SQL 2005 will be handled in on go
• TOC of SQL server 2008 is higher than the TOC of SQL server 2005
• Most of the remediation issue will be address at the intermediate migration
Kindly let me know your views about the best approach .
I am totally not following what you have there, sorry. When doing such upgrades though I:
1) take the minimum REQUIRED steps.
2) use the upgrade advisor prior to each upgrade, fixing as I go.
3) TEST THOROUGHLY ALONG EACH STEP!! The upgrade advisor isn't nearly a bullet-proof review!
4) NEVER do in-place upgrades. Depending on down-time needs there are several options available.
5) You MUST update ALL statistics with a FULL scan when upgrading. You get HORRIBLE query plans otherwise!
6) patch EVERYTHING up to the latest level on the new system BEFORE going there (this includes but is not limited to BIOS, all firmware, all drivers, all windows patches, all SQL Server patches, etc)
