I wanted to upgrade the version from 6.2 to 6.5 by on same existing 6.2 version server. When I go through document it was saying install 6.5 on new then follow the steps on backup and license to upgrade the version. But here i wanted to know, can we do install 6.5 on same existing working 6.2 version server then do the remaining backup and license part ? will that works or not. Please let me know.
Yes, you can use the same server to upgrade the version of Dynatrace to 6.5.
When installing the new services, you will have to keep it all down. During the migration you will shutdown 6.2 services, run the dtmigration to backup from 6.2 and then run it again to restore into 6.5. After that you can start 6.5 services.
At the instructions this is why it says: At the end of the installation, you're prompted to start the Server , Collector , and Client. Do not start these components at this time.
