Artifactory 6.9.0 provides backward compatibility for packages created with Conan server API v1 by automatically migrating the Conan server API v1 binary layout to the new format.
Migration to Conan server API V2 starts after the upgrade process is complete (in all nodes in case of High Availability) and all Conan API endpoints are blocked and cannot be accessed.
After migration, the default revision for all Conan server API v1 packages is set to "0" for both Recipe revision and Package revision, and endpoints will be accessible again.
By default, two threads are dedicated for the migration job. Before upgrading from versions previous to Artifactory 6.9, you can modify this setting in the $JFROG_HOME/artifactory/etc/artifactory.system.properties file ($JFROG_HOME/artifactory/var/etc/artifactory/artifactory.system.properties if modifying 7.x).
Note that you can allocate more threads during the migration process but need to restart Artifactory.
artifactory.conan.v2.migration.job.queue.workers = 2 (default)
