Upgrade JIRA with Ansible?

[Kumar Gajapaka]

Upgrading JIRA by running Ansible Playbook.

I wrote the ansible playbook for upgrading Jira and I'm using the bin installer in the Yaml file. When I run the playbook Jira is just upgrading to new version and backing up home directory. But I would like to know how to pass parameters by using silent Installation in Response.varfile and also the files which we modified have to include all the time in the playbook. 

My questions are :

1. Is that possible to upgrade Jira using Ansible.

2. How to compare modified/new files to existing/old files in the playbook

3. I didn't see any newly added files after upgrade in the playbook. 

Can anyone help me out.
