We are planning to update from Pega 7.1.5 to Pega 7.3.0/1 . We have downloaded the following installer files from PDN -

1. 115488_Pega7.3 and

2. 115631_Pega7.31

Both of these archive files contain <installer file location>/scripts/upgrade.sh/bat . But, I can not find any update.sh/bat script in either of these archive files.

But, as per document - https://docs-previous.pega.com/pega-731-platform-update-guide [Page-30], we have to execute update.sh/bat script. Where can I get the update.sh script ? Or we have to execute upgrade.sh script?

Note - we are planning to execute the script using command line in Linux server.
