RE: Upgrade options from 6.5.6? Gregg Eldred 2.Mar.11 03:17 PM a Web browser Domino Server All ReleasesWindows 2003
Doug has taken the added step of using TeamStudio, with which I agree (not affiliated in any way with them).
If you want a "high level," run the 8.5.2 installer, follow the prompts, and within a few minutes, your server will be upgraded to 8.5.2. Then, make some changes to the notes.ini, like adding Create_R8_Databases=1 and removing R6.x settings.
Bring up the server and watch for errors.
Then, apply FP1 to the server.
Later, you can convert the files to the new ODS and the mail files to the new R8.5 template.
