Unable to retrieve the required update sets from source to target instanceIssue Retrieve update sets UI action is retrieving only a small number of update sets from source instance into target instance.CauseIf the update sets on the source instance were updated over 90 days ago, these will also not be retrieved since the default value of system property 'glide.update_set.retrieve_days' is 90.ResolutionSetting the value of system property 'glide.update_set.retrieve_days' to 0 and clearing the cache on the target instance resolved the issue. Then all the update sets were retrieved from source instance into target instance.
