Install patches before upgrade

[JohnRumball]

I am planning to upgrade from AM 8.2 to 8.4.

I understand that I need to follow this path to accomplish this: 8.2 > 8.2 SP1 > 8.3 > 8.4

My question is, do I need to install the latest patch for the current version, before upgrading to the next version?

In other words, do I need to install 8.2 patch 5, before upgrading to 8.2 SP1?  And then 8.2 SP1 patch 8 before upgrading to 8.3, etc.

Also, my installation is comprised of a primary and one replica instance.  While the upgrade for one instance is running, does the other instance service authentication requests, therefor providing zero downtime of services during an upgrade?

Thanks in advance.

John Rumball‌,

As you mentioned the upgrade path from Authentication Manager 8.2 to 8.4 is 8.2 > 8.2 SP1 > 8.3 > 8.4.  As long as you are on the base versions of those versions, you do not need to be at the latest patch level to move to the next version.  See our documentation on Upgrading RSA Authentication Manager for more informaion.

While you upgrade one of your Authentication Manager servers, the other instances in your deployment will continue to serve your users' authentication requests.  Be sure to following the instructions on how to upgrade your servers as documented in the RSA Authentication Manager Setup and Configuration Guide for that version as you go through the upgreade process.

Regards,

Erica

The "Upgrading RSA Authentication Manager" topic at https://community.rsa.com/docs/DOC-100620 has been updated to answer both questions: "Do you need to apply patches before upgrading?" (Not usually) and "Can authentication continue normally or close to normally during an upgrade?" (Yes, if you have more than one server).
