GPL on target customer servers for the jar file

GPL is always a little foggy around this area but I’d like to ask you guys.

We have an installer that will need to update database on customer sites.  Can we install the liquibase jar onto the customer machine and perform the DB updates?  Do I need to remove the jar file after I’m done (im ok with this).  Am I allowed to even plop that jar file on the target server? 


LiquiBase is licensed under the LGPL which means you can use it and distribute it in any application without affecting your application’s license.  The LGPL only requires that any changes you makes to liquibase itself be offered back to the community.
