When retrieving multiple packages using Ad-Hoc Package Retrieval there is no way to set the order in which the packages are retrieved. If different packages contain different versions of the same document and/or its indexed values this could result in older versions replacing the newer versions. For this reason, it is a best practice to perform Ad Hoc Package Retrievals one package at a time so that you can ensure they are received and archived in the correct order.
Sending and receiving sites may experience slower system performance during package transfers, depending on the size of the package and the amount of system resources available at the time of the transfer. Receiving sites should coordinate package retrievals with the sending site before initiating the process to ensure minimal performance issues during the package transfer process.
