<div>Hi All,</div>
<div> </div>
<div>I'm struggling to find documentation on how I perform a rollback of a unsuccessful OTP hot deployment. I'm currently manually creating my .appup file with upgrade and downgrade instructions and when I perform a release_handler:install_release("someApp") my application hot deploys successfully, excellent! What i cant figure out however is if there were a problem following an upgrade how I downgrade / rollback to the previous release? Ive tried release_handler:remove_release("someApp") unsuccessfully as my upgrade remains active and I understand that I can restart OTP before making the upgrade permanent however in the environment I'm working in a restart would be unacceptable.</div>
<div> </div>
<div>How do I downgrade / rollback a hot deployment without restarting OTP?</div>
<div> </div>
<div>Many thanks,</div>
<div> </div>
