1/ UPDATE -- Mirror contract migration details for Columbus-5.

Below, we detail the steps for the execution of the Mirror contracts migration to Columbus-5 relevant to both DEVELOPERS and USERS.

Please follow the instructions and details attentively.

2/ In preparation for the migration to the Col-5 mainnet, the Columbus-4 network is expected to halt at block height #4,724,000 on Columbus-4 (~09/29 PST).

The migration process will take approximately 2 hours, but with the possibility of delays under extenuating circumstances

3/ Please note that Mirror Protocol and relevant products and developer tools will NOT be accessible during the migration process.

Any attempt to access these products may lead to a permanent loss of funds.

Again, do NOT interact with Mirror during the migration period.

4/ We will provide extensive communication around the process in real-time.

Mirror products that are affected during the migration period include:

- Mirror.js
- Mirror CLI
- Mirror Graph

5/ IMPORTANT -- The Mirror oracle price feed will also be halted while the Columbus-5 migration is underway.

This creates a situation that USERS need to be explicitly aware of and take the steps detailed below.

6/ To prevent potential liquidation situations from volatility in the underlying collateral during this phase, the price feed will be immediately stopped once the Col-4 network is halted and will not resume for another 3 HOURS AFTER the migration finishes.

7/ Users can deposit more collateral to increase their collateral ratio of borrow or short positions even when the oracle price feed is halted during this 3-hour window.

8/ It’s STRONGLY advised that USERS take precautionary measures to manage borrow and short positions BEFORE the Columbus-4 chain is halted OR during the 3-hour window period AFTER the chain is halted to minimize liquidation possibilities.

9/ A modified version of the Mirror web app will be accessible after the Col-5 migration is complete.

10/ While the price oracle feeder is stopped, any actions to mint/burn mAssets, withdraw collateral, or close borrow or short positions will not be available until the price feed is resumed AFTER the 3-hour window concludes.

11/ Finally, an update on the Mirror contracts on the Bombay-10 testnet:

To all DEVELOPERS using Mirror contracts & Mirror.js, please prepare to migrate your contracts and apps before Terra's Columbus-5 update by testing and modifying your services on the Bombay-10 testnet.

12/ Resources and instructions can be found below:

New contract codes are available on the main branch of the link below. github.com/Mirror-Protoco…

Contract migration guide for Columbus-5 can be found on the link below: github.com/terra-money/ma…

13/ If you built an application using Mirror.js, please make sure to check out the Bombay-10 compatible version.

Be sure to test your application on Bombay-10 so that it will be ready for the Columbus-5 migration: - Import: "@mirror-protocol/mirror.js": "^2.1.0"

14/ The above details should be followed meticulously.

We ask the #LUNAtics to please help disseminate this information as much as possible to minimize the chance of users losing funds during the Col-5 migration as we cannot intervene once the process is initiated.

15/ Please stay tuned for more information about Mirror’s migration for Columbus-5.

We will provide transparent and thorough communication around the migration process in real-time to help ensure the smoothest rollout possible.
