-----------------------------------
Summary: Support merging content during upgrade
Key: OAK-2619
URL: https://issues.apache.org/jira/browse/OAK-2619
Project: Jackrabbit Oak
Issue Type: New Feature
Components: upgrade
Affects Versions: 1.1.7
Reporter: Julian Sedding
Priority: Minor
When upgrading from Jackrabbit 2 to Oak there are several scenarios that could
benefit from the ability to merge content rather than overwrite it. Especially
in combination with OAK-2586, i.e. support to include/exclude selected paths
from the copy operation, merging can become very useful.
# Start vanilla product with an empty repo that writes some initial content,
then copy content from a Jackrabbit 2 repo into this instance
# Unify content from several Jackrabbit 2 repositories into a single Oak repo
# Copy all content 1 week before the actual migration, then merge in the diff
on migration day
