Upgrade Procedure?

We currently have version 2.6 running our server.  What is the upgrade procedure to get to v2.8.7

Thanks.

Hi Jason,
The database design is slightly modified with version 2.8 so you should run a small update script to fix your current database. Then you should replace the files (other than the updated database and inc_config.asp if you had modified the default one) with the ones included in the package of version 2.8.7 . I am sending you the package of version 2.8.7 and also the update script via email now. Other customers may contact me for the files if they want to upgrade to this version.
