9.3. Frequently Asked Questions

This section answers some common questions about the LOCKSS system.

I have an existing classic LOCKSS system (version 1.x). Can I upgrade to LOCKSS 2.0-alpha6?

The LOCKSS 2.0-alpha6 release is a technology preview which we are excited to share with the community for testing purposes. It is not yet possible to convert from a classic LOCKSS system (e.g. version 1.76.4) to a LOCKSS 2.0 system for production purposes.

However, version 1.76 of the classic LOCKSS system contains a prototype tool to test the migration of archival units (AUs) from a production 1.76 system to a test 2.0-alpha6 system, for testing purposes. See https://github.com/lockss/community/wiki/Migration-Tool.

To help us advance toward the final LOCKSS 2.0 release, please consider installing and running the LOCKSS 2.0-alpha6 release on a test machine and providing us with your feedback.

I have a LOCKSS system running 2.0-alpha5. Can I upgrade to LOCKSS 2.0-alpha6?

Yes. You are welcome to wipe your testing data from LOCKSS 2.0-alpha6 and start from scratch, but there is an upgrade path from LOCKSS 2.0-alpha5.

Can I use my own PostgreSQL database? Can I use my own Solr database?

Yes, you can configure the system to use your institution's Postgres database and/or Solr database -- or you can simply let system run included ones locally.

Can I replay Web content with my own Pywb instance? Can I replay Web content with my own OpenWayback instance?

Yes, you can configure your own Pywb instance and/or OpenWayback instance to connect directly to the LOCKSS Repository Service -- or you can let the system run included ones locally, or you can choose not to run any Web replay engine at all.
