3. Preparing Your LOCKSS 2.x Host

The next task in the migration process is to prepare your LOCKSS 2.x host [1]. The necessary work depends on your Migration Scenario:

If you are doing a new-host migration, you will need to commission the new host. This could mean:

  • Setting up a new physical machine and installing Linux.

  • Spinning up a new Linux virtual machine.

See the System Prerequisites chapter of the LOCKSS System Manual for guidance about CPU, Memory, Storage, and Operating System requirements.

If you are doing a same-host migration, you may need to upgrade your operating system before you can co-install LOCKSS 2.x with LOCKSS 1.x.

Many LOCKSS 1.x hosts are currently running RHEL 7-compatible operating systems (such as RHEL 7, CentOS 7, Oracle Linux 7), or CentOS 8-like operating systems (CentOS 8, CentOS Stream 8), which have all reached end of life. If your host is running one of these operating systems, you must upgrade to a RHEL 8-compatible or RHEL 9-compatible operating system (such as Rocky Linux 8 or 9, AlmaLinux OS 8 or 9, Oracle Linux 8 or 9, RHEL 8 or 9, etc.) before you can install LOCKSS 2.x on that host.

The LOCKSS Community Wiki offers a page on OS Upgrades, providing guidance on various upgrade paths.
