upgrading from lightweight forwarder to universal forwarder

Just checking we are planning on upgrading a lightweight forwarder to a universal forwarder.
the plan is
install the universal forwarder
create the /opt/splunkforwarder/old_splunk.seed
Set a deployment server in /opt/splunkforwarder/etc/system/local/deploymentclient.conf
start the universal forwarder.

What I am wondering, will the checkpoint file be honored, if I start the server then wait for the deployment server to send apps the universal forwarder. The app contains the indexes and inputs etc for each of the feeds that the server needs.

Thanks

Yes, the checkpoint file will be honored, but back up your configs as changes don't occur until restart of splunk. Also verify the $SPLUNK_HOME/var/log/splunk/migration.log, this will tell you which files have been modified. What you are mostly concered about is the fishbucket directory.

Hope this helps or gets you started.
