## Motivation
> With the Aave v3 linear pool wrappers ready for deployment in the ecosystem various Boosted Aave v3 pools and pairings have started to crop up in the governance forum. In order to streamline the process of transitioning from the old Aave v2 pool and pairings I on behalf of the Maxis am proposing we close the loop by voting to kill the relevant gauges this week thereby permitting 3 more weeks of emissions on the pool gauges listed below. This will give LPs enough time to migrate their positions and new pools to bootstrap themselves in the BIP-19 cycles. As an adder, a new STG/bb-a-USD gauge will be activated with the execution of this proposal, along with the old one added to the kill list. The STG/bb-a-USD pool will be killed but the same information applies as in [BIP-105.](https://forum.balancer.fi/t/bip-105-enable-stg-bb-a-usd-gauge-ethereum/3905)
We will be coordinating with the various bribe marketplaces to ensure all future voting incentives only go towards the new gauges. The old pools listed below will no longer have core pool status. All of the migrated pools will be restored as “core pools” under BIP-19.
## Pools being migrated:
Original deployment → New pool address

### Adding STG/bb-a-USD Gauge (Ethereum)

#### Transaction:
_To allow time for emissions to move over and all LP’s to get the full benefit of AURA emissions this BIP will be executed in two parts. Part A will add the new bbaUSD/STG gauge and be executed immediately. Part B will kill the gauges outlined above and be executed on May 2nd._
Part A:
The DAO Multisig `0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will interact with the AuthorizerAdaptor at `0x8F42aDBbA1B16EaAE3BB5754915E0D06059aDd75` and call performAction with the GaugeController at `0xC128468b7Ce63eA702C1f104D55A2566b13D3ABD` for the target(address) argument and using 0x3a04f900 followed by the gauge address `0x454eb2f12242397688DbfdA241487e67ed80507a` and the corresponding gauge type for the data(bytes) argument.
data(bytes) : `0x3a04f900000000000000000000000000454eb2f12242397688DbfdA241487e67ed80507a00000000000000000000000000000000000000000000000000000000000000002`
### Killing Old Gauges
Part B:
