Adobe Acrobat Pro 2017 perpetual licensing for corporate

Hi,

I am using Acrobat XI since long and having perpetual license under Adobe VIP.

Now, Acrobat displaying alerting me that the Security updates, technical support, and bug fixes are no longer available as Adobe Actobat XI End of Support.

While contacting the platinum partner of Adobe to get the perpetual license of Acrobat XI upgrade to Acrobat 2017, I learnt that the "Perpetual lic. Is not  for Corporate Customer".

Keeping in view of the above, can any one suggests me what to do with the existing copy of Acrobat XI??
