Upgrade, not Update if using IAC? (Pega 7.1.4 to Pega 7.1.9)

Hello Upgrade Center experts,

We are planning to upgrade from Pega 7.1.4 to Pega 7.1.9 or later. As part of this, we would also upgrade CPM, CPMFS Strategic Applications. We use IAC extensively and also have BIX installed.

I thought, move from Pega 7.1.4 to latest version of Pega 7.1.x is considered ML Update and have to use "Pega719_UpdateGuide.pdf" guide; however in the same document on Page 4, it says the below:


Updates do not include additional products: You must upgrade if your system includes Pega Web Mashup (formerly Internet Application Composer (IAC) or Business Intelligence Exchange


Question 1: Please confirm as per above statement, if we must follow the Upgrade guide "Pega719_UpgradeGuide.pdf", not Update guide, because we use IAC.

Question 2: The version of IAC and BIX provided, "pxBIX_07.10.01.zip" under Additional_Products folder, as part of distribution package in 7.1.4 & 7.1.9 seems to be same.

Even if it's not same, the Pega-BIX ruleset jar can be deployed independently after performing an Update from Pega 7.1.4 to Pega 7.1.9. So, I do not understand the reason for performing Upgrade, instead of Update, if we use BIX.

Is this because, core Pega engine code has undergone BIX related changes from 7.1.4 to 7.1.9, not just Pega-BIX ruleset? Please clarify.

Look forward to your replies.

Because the update distribution does not include any additional products, like BIX, and because all the product components must be at the same release version, if you want to move to the Pega 7.1.9 Platform with BIX, you need to Upgrade.  See the Pega 7.1.9 Platform Upgrade Guide on the PDN for instructions.

After update is completed you can go-ahed and perform the additional components update from the 7.1.9 Full Distribution Image.

Update is little bit igher than upgrade process and it takes less time to complete. Apart from this there is no functionality you will miss either you go through the Update or Upgrade Process.

Thanks for confirming that we can just do Update (from Pega 7.1.4 to Pega 7.2), and install BIX jar / IAC war files from Full Distribution package.
