OSSRH Migration - Few clarifications and guidance

Hello,

We received an email from Eclipse Foundation on OSSRH migration and we've internally discussed and understand that the following are the activities we might need to do post the migration activity is completed,

1. Change oss.sonatype.org to central.sonatype.org in workflows.
2. Updating all POM files in Distribution management section to point to server central.sonatype.org
3. Document update for Build Guidelines in ecsp-website - for reflecting central.sonatype.org

We would like to understand if there are any more things we need to take care. Please clarify on the following,

1. What will happen to the GPG signing and the private key used to push libraries to maven central (central.sonatype.org)?
2. Will you be providing steps to be followed for the migration activities?

Thanks,

Prem
