This team is working diligently to finalize this solution and we anticipate publishing a couple of corrective patches in our website ( ) by Friday March 15th 2019 with further instructions on what our valued customers can do to avoid any negative outcome when the rollover occurs.

The entire Orolia family sincerely appreciates your patience and understanding while we work through this process and provide a solution with minimum impact on your networks. We look forward to communicating with you again on March 15th.
