New Best Practices Whitepaper published: "Database Mirroring and Log Shipping Working Together"
Log shipping and database mirroring can work together to provide solutions for high availability and disaster recovery. You can convert an existing log shipping configuration to a database mirroring configuration. Although Microsoft only supports a single mirror database, you can set up log shipping from a database mirroring pair to additional servers, to provide multiple failover sites. Moreover, you can easily switch which pair of instances is using database mirroring and which instances are configured with log shipping.
