The following instructions apply ONLY 
when upgrading from wbTeamPro v1.x to v2.x. 
The location of files with the wbTeamPro v2 system have changed, and the presence of both the old and new wbTeamPro system will cause a system conflict.
To prepare your existing installation for the new wbTeamPro v2 system you will need to perform the following:
- Remove Admin Template Modifications- /{whmcs}/admin/templates/blend/header.tpl
 /{whmcs}/admin/templates/original/header.tpl
 /{whmcs}/admin/templates/v4/header.tpl
 Find and remove the lines:
 {* wbTeamPro Customization *}
 {include_php file="AddOns/_wbteampro_/tmpl/header.php"}
- /{whmcs}/admin/templates/blend/header.tpl
 /{whmcs}/admin/templates/original/header.tpl
 /{whmcs}/admin/templates/v4/menu.tpl
 Find and remove the lines:
 {* wbTeamPro Customization *}
 {include_php file="AddOns/_wbteampro_/tmpl/menu.php"}
- /{whmcs}/admin/templates/original/sidebar.tpl
 /{whmcs}/admin/templates/v4/sidebar.tpl
 Find and remove the lines:
 {* wbTeamPro Customization *}
 {include_php file="AddOns/_wbteampro_/tmpl/sidebar.php"}
 
 
- /{whmcs}/admin/templates/blend/header.tpl
- Remove Client Template Modifications
 
 - /{whmcs}/templates/classic/header.tpl
 /{whmcs}/templates/default/header.tpl
 /{whmcs}/templates/portal/header.tpl
 Find and remove the lines:
 {* wbTeamPro Customization *}
 {include_php file="AddOns/_wbteampro_/tmpl/header.php"}
 
- /{whmcs}/templates/classic/header.tpl
- Rename the Existing Admin wbTeamPro Folders
 Rename
 /{whmcs}/admin/AddOns/_wbteampro_/
 to
 /{whmcs}/admin/AddOns/_wbteampro_backup/
 *NOTE* The new installation will look for the above backup folder in order to import your configuration and attachments.
- Rename the Existing Client wbTeamPro Folders
 
 Rename
 /{whmcs}/AddOns/_wbteampro_/
 
 to
 /{whmcs}/AddOns/_wbteampro_backup/
 *NOTE* The new installation will look for the above backup folder in order to import your configuration and attachments.
 
- Re-Issue your wbTeamPro License
 
 When upgrading from wbTeamPro v1.x to v2.x you will need to re-issue the license under the "My Services" area of our billing system. Login to our billing system @ http://billing.holodyn.com/, login to your client account, then visit the "My Services" section and open the wbTeamPro service record. You will see a "Reissue License" button above the available downloads section. This will reset the license on our server allowing the new v2.x to perform a fresh verification.
You have now disabled the previous installation of wbTeamPro
and can continue with the wbTeamPro v2 installation instructions.
