Event Replicator - Change data capture files

Dear all,

Currently we are planning to use the EV replicator as one of the tool to capture the changes from legacy (Adabas) and stage it to Datawarehouse ,can you please let me know is there any standards best practices to achieve this.
We are using Oracle database as staging area. we have a significant source data 15 years worth from Adabas :x

Thanks in advance
