Is there a way to export and import content from one sulu (1.6) installation to another? Let's say from a staging system to the production version?
Maybe the doctrine commands will help you.
!!! IMPORTANT !!! THIS IS A FULL COPY WHICH DELETES EXISTING DATA FROM TARGET INSTALLATION
Export from Staging:
bin/adminconsole doctrine:phpcr:workspace:export -p /cmf cmf.xml
bin/websiteconsole doctrine:phpcr:workspace:export -p /cmf cmf_live.xml
bin/adminconsole doctrine:phpcr:workspace:export -p /jcr:versions jcr.xml
Delete everything in the target installation (in your case production):
bin/adminconsole doctrine:phpcr:node:remove /cmf
bin/websiteconsole doctrine:phpcr:node:remove /cmf
bin/adminconsole doctrine:phpcr:node:remove /jcr:versions
Import into the target installation:
bin/adminconsole doctrine:phpcr:workspace:import -p / cmf.xml
bin/websiteconsole doctrine:phpcr:workspace:import -p / cmf_live.xml
bin/adminconsole doctrine:phpcr:workspace:import -p / jcr.xml
Also don't forget to copy the database and your uploads folder (var/uploads/)
