Export file missing version information. No migration will be performed.
When importing an new version of a custom extension the Extension Manager shows "import successfull" however the lib is not replaced in the filesystem (old vers. still exists). Also the ThingTemplates are the ones from the old version.
The message in the log file reads: Export file missing version information. No migration will be performed.
Only stopping the Apache Tomcat service, removing the old jar by hand and then restarting service and importing new extension version help.
Is there a way to use the import manager to overwrite the extensions with the new version without having to delete the old version manually?
