- Check your sql7 service pac for the prereqs !

- Start with SQL2005 Upgrade advisor !

- run dbcc checkdb for all databases;

- if you can , don't upgrade, but migrate (i.e. make a fresh install of sql2005 , copy the users, grant the windows logins and then copy db per db.Don't forget the jobs !)

- pay special attention to DTS-packages.

Why are you saying don't upgrade, but migrate

What are the reasons for this ? Any known problems ?

Thanks.

Indeed.

-If you can, migrate;

Reasons:

- in case of disaster you'll have to build your server exactly as your current server. i.e. start with install sql 7.0, restore your sql7.0 databases, then upgrade to sql2005 and restore your sql2005 databases !

The reason for this is security. When upgrading, SQLserver keeps the security settings,so everything will continue to work with then niew version/settings.

-If you start with a fresh sql2005 install, you'll have to open it up yourself (and document that ! )

Take the time to investigate the new security advises.
