You can check the Compatibility Chart to ensure that Ledger 9.0B will be compatible with your other modules. You will definitely need to be at 9.0B of Lanpak as well and there is an 091110 release of Ledger 9.0B that you may want to speak to your Adagio Consultant about.

Bear in mind that the absolute best way to recover from a crash during posting it to restore the backup made immediately prior to posting - why don't you try that. There's no guarantee that Ledger 9.0B will repair the data so you may still need to have the Data Repaired.
