Just wanted to ask one more time if there’s any additional guidance or if anyone else has completed this upgrade.
If the procedure I outlined below looks correct, my one question is if I should updated the hosts to 4.5.7 before deploying the new hosted-engine? Or should I deploy and update a new hosted-engine before updating the actual hosts to 4.5.7? Thanks, Devin > On Jan 20, 2026, at 10:15 AM, Devin A. Bougie <[email protected]> > wrote: > > Hi, All.
