The same user posted this information on Facebook which he got from VM:

"Thank you for clarifying, and I do understand what you're saying.
I appreciate that you do not wish to move to TV 360 and that you were advised at the time of renewing your contract that an upgrade wouldn’t be required.
The email you've received has been sent because the V6 box is part of our older TV platform, and upgrades to TV 360 are currently being encouraged. However, I completely understand your concerns and preference to remain with your existing setup.
If you're happy with your current V6 box and do not wish to upgrade to TV 360, you can continue using your existing box for the time being. There is nothing on the account to suggest that your services will be affected because of this.
I've checked the account, and I can reassure you that there is currently no date showing on the account for your V6 box to be switched off or for your TV services to be disconnected.
While Virgin Media is encouraging customers to upgrade to TV 360, there is nothing on your account indicating that you must upgrade by a specific date or that your services will stop if you choose to continue using your V6 box."
