# Modifying Builder Subnets

## Transferring Ownership of a Subnet

{% hint style="warning" %}
V1 Subnets cannot be transferred from one address to another.
{% endhint %}

## Upgrading Subnets

{% hint style="warning" %}
Subnets are not automatically upgraded to the next version of the Builder Contract. When a new Builder Contract is released, Subnets are required to register a new Subnet.
{% endhint %}

## Editing Subnet Configurations

{% hint style="warning" %}
Subnet data and parameters are immutable once the Start Date is passed. If you need to change immutable subnet configurations you will need to register a new Subnet.
