We are in the process of planning to migrate databases from SQL 2000 to SQL 2008. What's the best option to approach this with little downtime? Users would like to have access to the data on the SQL 2008 server to continue with their testing before the cut over. The only option that I can think of will be transaction replication. Any other ideas? Thank you

1. Backup and t-log restore
2. Transactional replication

what about backup and restore? Is any downtime allowed? You may need to think about a specific cutover date \ time , migrate onto new environment , and reconnect users.
Have you analysed any upgrade issues>

Hi Jack, and thank you for your response. Backup and restore would work but we would like to run both environments side by side and compare data. In terms of downtime, we haven't decided on that yet but I'm sure 4 - 6 hours. Would replication not work?

Hi Kyang, yes replication will work. The reason I've mentioned backupo and restore - as it is very easy , and will require little setup time.
