I'm trying to migrate Oracle Calendar Resources using ics files, migtool and RET procedure.
I created the resources but when I try to import the data using the command below I get the following error message half way through the import. Please help:

curl -k -u adminassword --data-binary @/var/tmp/resources/resource1.ics.zimbra 'https://server1.domainx.com:7071/service/home/resource1@domainx.com/calendar?fmt=ics'
