The LOCKSS Program is pleased to announce that LOCKSS 1.79.14 (the first release of LOCKSS 1.79) and LOCKSS 2.0.91-beta2 (the first release of LOCKSS 2.0-beta2) are now available, a twin release that officially ushers in the era of LOCKSS 1.x to 2.x migrations in the Global LOCKSS Network (GLN) and CLOCKSS.

When LOCKSS 1.78 and LOCKSS 2.0-beta1 were previously released containing the LOCKSS 1.78 to LOCKSS 2.0-beta1 Migrator, users of LOCKSS 1.x were invited to become early adopters of LOCKSS 2.x -- but not users of LOCKSS 1.x in the GLN and CLOCKSS. This is because the much larger scope of GLN and CLOCKSS migrations required further software development to handle lengthy migrations of this size and complexity, at an acceptable throughput, without interruption of service. Indeed, LOCKSS nodes for such jumbo applications span hundred of millions of objects and hundreds of terabytes of content storage, under heavy service loads and in mission-critical workflows. The substantial development effort focused on scalability and concurrency took the LOCKSS engineering team the better part of two years.

We are excited to invite LOCKSS 1.x users in the GLN to join the early adopters of LOCKSS 2.x. With this release comes an updated LOCKSS 1.x to 2.x Migration Guide on the LOCKSS Documentation Portal, including a comprehensive introduction for system administrators, a section for end users, and a dedicated section for administrators of LOCKSS networks. Although anyone is welcome to apply the instructions in the migration guide on their own (and we would love to get feedback, to correct any errors and improve the wording), we would appreciate the opportunity to discuss migrations with users of LOCKSS 1.x, both to provide technical support and to help us improve our user community's experience with the migrator.

We are also excited to implement CLOCKSS' migration plan to LOCKSS 2.x. As the most intensive power user of LOCKSS technology, CLOCKSS has been an invaluable partner in this development cycle, providing the most demanding use cases for scalability in the repository, concurrency in the metadata database, and performance in the migrator.

Interested in beginning a migration from LOCKSS 1.x to 2.x? Contact us, we will be glad to help!
