Hi Vasu,
When using ILM Retention Management, you are applying retention rules to only those archive objects that you choose to. Again, there is no ILM stand alone server. You activate ILM via the switch framework within your ECC system. You also have to have an ILM certified WebDAV server to store the ILM store files. If you have already started data archiving, you can migrate/convert these ADK files into ILM store files which will now have the retention rules applied that have been configured for the archive objects you have chosen. By activating ILM, you have not affected or applied retention rules on live ECC data.
Please review the available SAP ILM help documentation and hope it helps to explain it in more detail.
For some reason I am having issues inserting a hyperlink so will try and type out the link to the help documentation.
Best Regards,
Karin Tillotson
