### Motivation

As part of the coming migration to the Timelock Authorizer described in [BIP-140](https://forum.balancer.fi/t/bip-140-introduce-timelockauthorizer/4159) the [Gauge Adder v2](https://forum.balancer.fi/t/bip-29-introduce-gaugeadder-v2/3490) also must undergo a migration to be compatible with the new authorizer.

The only differences from the old one is

- that it supports the new authorizer that we’re migrating to (old one will break after migration)
- it allows multiple gauges per pool on ethereum mainnet now.

### Specification

If approved, the DAO Multisig `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will initiate a transaction to interact with the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` calling `grantRole` with the following arguments:

role: `0x0000000000000000000000000000000000000000000000000000000000000000`

address: `0xE0f34c6AD719e6877062B7D97E12c61c096509AF`

This can be verified [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/tasks/scripts/20230109-gauge-adder-migration-v2-to-v3/output/mainnet.json).

Additionally, the code for this migration can be viewed [here](https://github.com/balancer-labs/balancer-v2-monorepo/blob/35332c744be8a684881512e%5B%E2%80%A6%5Duge-adder-migration-v2-to-v3/GaugeAdderMigrationCoordinator.sol).

In order to execute the migration, the DAO Multisig `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will initiate a transaction to interact with the GaugeAdderMigrationCoordinator `0xE0f34c6AD719e6877062B7D97E12c61c096509AF` calling `performNextStage()`

Note that if this passes the example will need to be updated with the new addr address here:

yep good call out.

new address will be here [balancer-v2-monorepo/mainnet.json at master · balancer-labs/balancer-v2-monorepo · GitHub](https://github.com/balancer-labs/balancer-v2-monorepo/blob/master/pkg/deployments/tasks/20230109-gauge-adder-v3/output/mainnet.json)

will be in force once the timelock authorizer is turned on
