Hi;

We have an EV server installed on windows 2003 server and the version is 9.0.1. Sql also installed on the same machine

We want to move it to a new windows 2008 server and also want to upgrade the version of ev to 10.0.2

Is the following steps are okey for our envirement.

1. upgrade the old ev to 10.0.2

2. add the new ev as an additional EV server to the site

3. move the archives to the new site

4. after all the archives moved Move SQL databases off EV to the new server.

This is an urgent issue.  Are there any body to help me?
