Hi,  I want to utilize the OOB archive/Purge/Expunge features and define a standard archival process for all applications. I was able to test this feature successfully and archive the file to Amazon S3 bucket. The archival is creating a zip file and csv file with it inside. The blob data is all encrypted in to a column in csv file. How can we read this data from csv blob in case of audits. Even though we archive the data that is most likely not accessed again, we need to have a way to do that before we standardize our archiving process. Also, for the case types (applications) which do not have case types defined in old versions, how can we create data retention policies when we migrate to 8.7 as it seems defining the archival setting in case type is the only way to define archival policy.
