Hi Team,

Till now we are using upgrade.sh script to upgrade our pega versions to the latest.

In below doc I am unable to found upgrade.sh script info and I feel it was filled with update.sh script.

> **[Pegasystems Documentation](https://docs.pega.com/bundle/archive/page/archive/topics/archive-directory.htmlpega-platform-87-update-guide-apache-tomcat-and-ibm-db2-linux-unix-and-windows)**

Do we need to change the script to update or upgrade.sh can be run for 8.3 or 8.4 or 8.5 to 8.7.4 or 8.8.1 upgrade pega version ?

Thanks.

@HARIL043

I checked with the Start Here file that comes bundled with 8.8.1 and found the following, which indicates that you can continue to use upgrade.sh:

_The Installation and Upgrade Assistant tool requires a Java runtime environment. The command line scripts equivalents are in the /scripts directory of the Pega Platform media named: install.bat, install.sh, upgrade.bat, and **upgrade.sh**._

Here is a full view of the Start Here file:
