Drupal 7 based Portal - PHP 7.3.15 security issues validations

Hi Dino! Thanks for your response!
I have a query with regards to validations post PHP upgrade.

Could you please let me know if we have to perform any specific steps to validate PHP compatibility. (Post upgrade). For your review, I have added steps below, which I followed last time.

What I did in last upgrade:

  1. Taken Drupal backups - File System level and MySQL dumps.

  2. Upgraded PHP.

  3. Verified the accessibility of portal, confirmed status report and updated PHP version information there. Validated critical and errors logs. Made sure traffic is following by reviewing Apache error logs and Drupal Access logs.

thanks,

Imran
