DNS Migration and OneDrive Cleanup

I need help migrating DNS records and clearing my OneDrive system.

DNS Migration:
- Records: MX, CNAME, and TXT
- Ensure minimal downtime, migrate GoDaddy to Ionos, and point GHL and WIX there.
-SSL certificate for multiple domains on Ionos

OneDrive Cleanup:
- Delete unaccessible accounts
- Give access to teams to existing accounts and future ones

Experience in DNS management and OneDrive is essential. Please include relevant experience in your application. Backup knowledge is a plus.
