We are re-architecting the data store for our Adobe Experience Manager (AEM) platform and have an encountered an issue when attempting to perform sidegrades using the oak-upgrade jar. We're currently on AEM 6.5.13 which uses Jackrabbit Oak 1.22.11. The current datastore contains content and assets in a segment store. In the new architecture, content will remain in the segment store, but assets (binaries) will live in an external data store.
We refrained from doing a live migration because the current platform is used 24/7 by our global marketing team and we wanted to minimize the impact to their day-to-day activities. We take a snapshot of the current repository, move it to the new server, and run local migrations there. The initial migration worked fine despite the indexing taking 81 days, but the main problem is that every time we attempt to perform a migration with only deltas, it continues to perform a full migration and duplicate the copying of nodes that already exist in the new repository. We're using the following commands to migrate the content and the assets (the full paths have been redacted for security purposes) : Content /../../java/jdk1.8.0_162/bin/java \ -server \ -Djava.awt.headless=true \ -Xmx48G \ -jar /../oak-upgrade-1.22.11.jar \ /../source/author/crx-quickstart/repository \ /../target/author/crx-quickstart/repository \ --src-datastore=/../source/crx-quickstart/repository \ --datastore=/../target/crx-quickstart/repository \ --include-paths=/foo/bar,/foo1/bar1 \ --copy-orphaned-versions=false \ --copy-versions=2019-01-01 Assets /../java/jdk1.8.0_162/bin/java \ -server \ -Djava.awt.headless=true \ -Xmx48G \ -jar /../oak-upgrade-1.22.11.jar \ /../source/crx-quickstart/repository \ /../target/crx-quickstart/repository \ --include-paths=/foo/bar,/foo1/bar1 \ --copy-binaries \ --copy-versions=2025-01-01 \ --copy-orphaned-versions=false Any idea why it continues to do a full migration instead of a delta migration on subsequent sidegrades? Also is there anyway to bypass the re-indexing on the target system after every delta migration? Thanks in advance.
