@Anthony_Gourtay   There are no plans at present to release a new version of AES. PDC is preferred solution as it offers you better features, better support and a better price/cost (free!).

AES 83 runs on Platform 8.3 multiTenant and was developed and tested with Postgres and Tomcat. While AES 83 should 'just work' on any application server, there are postgres-specific features for managing data storage using postgres table partitioning. There are clients using AES 8.3 on Oracle - they have accepted responsibility for converting the code to use Oracle partitioning or to manage purge and storage management explicitly. 

Platform 852 can send alerts, exceptions and health status to AES 73 or AES 83 - the format has not changed. AES 73 has none of the features to interpret exceptions or raise observations based on PAL stats that are in AES, and will record but not 'understand'' any alert introduced by Platform 74, 81, 82, 83, 84, 85. AES 83 can accept data from platform 85 but will record but not interpret alerts added in platforms 84 and 85.

All versions of Pega Platform contain a 'PeaAESRemote' ruleset originally created for AES integration now used for PDC integration. The ruleset has always included agents to push usage data and index definitions to AES or PDC. PDC team has enhanced the agents to provide more meta-data regarding the runtime operating environment and added many new agent activities and REST connectors to send data to PDC. Most of the new agent activities are not functional when used with AES 73 - AESRemote will try to call services that do not exist in AES 73. Platform 852 includes a few agents & connector rules to call services added to PDC subsequent to AES 83 completion.
