communigator installation

We are looking to install Communigator Marketing software on our version of Sugar.
It seems that this software requires modules in version 7 of sugarcrm format in order to install.
We are currently running SugarCRM version 6.5.16 but would look to update to SuiteCRM if this solves our problem.
Does anyone know if SuiteCRM modules are compatible with SugarCRM 7 versions?
Has anyone had experience with Communigator on SuiteCRM/
