Joomla to WordPress Backend Migration

I have a website currently running Joomla 1.5 that needs to be migrated to wordpress.

I have very specific requirements that must be met.

My Joomla 1.5 site is a subscription site that is currently using a third party Joomla plugin called Account Expiration Control (AEC) to manage account expiration (http://valanx.org/index.php?option=com_zoo&view=item&layout=item&Itemid=118)

All users and expirations will need to be migrated to the third party plugin s2member Pro for Wordpress (http://www.s2member.com/)

I am also using a Joomla extension JForms that is just a form where user can input information into a log and they can go back to see all previous entries they have logged. This plugin works by linking the Joomla userid to the post. This will make migration difficult as the userids need to be updated to make the Wordpress userid. On the Wordpress side I plan on using either Formidable Pro (https://formidablepro.com) or Gravity Forms (http://www.gravityforms.com/) as the plugin to replace JForms

User passwords must also be migrated from Joomla to wordpress which I am hoping the Joomla to Wordpress Migrated User Authentication plugin (https://wordpress.org/plugins/joomla-to-wordpress-migrated-users-authentication-plugin/) will work

This will be a live site so all development will need to be ready and implemented all at once with little to no downtime.

To ensure you are reading my post in detail and understand my posting as the first part of your reply please list all Joomla plugins I am using and the corresponding wordpress plugin that needs to replace it. IF YOU DO NOT ANSWER THESE QUESTIONS YOUR APPLICATION WILL AUTOMATICALLY BE REJECTED.
