License expiration

Hello guys,

I am thinking about stopping licensing my ITMS 7.5 and DS 6.9 products in September, because maybe we are going to install Microsoft SCCM instead of ITMS 8.0 next motnhs.

My licenses ending end of september. 

Is this a good idea? Can my computers still get software, can I deploy computers with my expired license, and only support from Symantec is stopped, or is everything stop working?

Thanks for answer,

BR, David
