Hi, I just brought up an EC2 instance with Wz3 for testing to migrate from Wz2, but all our buckets are private and in Wz2 there was a property "awsAccessKeyId" and "awsSecretAccessKey" in conf/Server.xml that I filled in and everything worked, now this property is missing from Wz3, and the manual refers to a startup package that isn't included in the AMI...do I just copy the properties from the Wz2 instance and restart or is there something more involved that should be done?
