This should be doable, basically you set up a brand new account and contract at the new address, I assume that you own the new property and can agree to have the work done there, and arrange to be on site, when they want to turn up and install the interior cabling.
For a while you will be paying for two connections, the one at your old property and the one at the new, the latter should be cheaper as it will effectively be a 'new customer' deal. And then as you say, once moved, you give VM the required 30 day notice period and cancel the old contract.
All fine, but something you need to be aware of, maybe you are and it doesn't matter, from VM's perspective, there is no connection between the two contracts, nothing from the old one can be 'transferred' to the new one, it's a complete green field setup. And the thing that might be an issue is any VM branded email addresses associated with the old account. They will be lost; there is no possibility of 'moving' them to the new account. This may not be an issue, but if it is, then use the time to start shifting any and all accounts with other parties to a new email address.
Lastly "My contact ended Feb,2026."; was that a typo for 2025? If not then as soon as you cancel the old account, you will be hit with early disconnection charges.
