o 4.6.1 is really old. you should disable rsd, then upgrade to at least 4.6.8, then upgrade to 5.1.2
Thanks for your reply.. Can I upgrade 4.6.1 to 4.6.6 then to 5.1.2
We have licensed the ePO and Integrity Control v6.0 during the installation of 4.6.1
Are these license keys are valid or we need to buy any new license keys.
You do not need new license keys as long as your grant is active. You should be able to upgrade straight from 4.6.1 to 4.6.9. Ensure that you have backups of your ePO app server and your SQL database before performing the upgrade. Note if you want to then move to ePO 5.x, you have to go straight to 5.1.2 per McAfee KnowledgeBase - ePolicy Orchestrator 4.6.9 Known Issues
