Thanks for update RB.
We have tried this method as in we stop SAP and sync file systems and perform DB/Backup restore method. This method works but unfortunately I am not able to find any SAP relevant document to support this method for so called "java" systems.
SAP only suggest to perform system copy for "java" hence we are trying via export import. Currently I am looking into options of using old master installation software.
although, can i request you if you any SAP relevant note or kba or any other in which SAP support/suggest we can perform file system copy and db restore for "Java" systems then it will be just a thing which I need to go ahead with method you suggested.
Thanks , kindly update.
Warm Regards,
