Thank you Mauricio. We are on the verge of finalizing our porting strategy. We decided to port into JPDL only. Could you please help me with these questions. 1) To mitigate risks associated with JBPM5.3 (since released last month only), we would like to migrate process definition from ALBPM to JBPM3 and curious to know the support period for JBPM3. 2) As per our understanding JBOSS 5.0 should be used for JBPM3. Please advise, if JBPM3 is supported by later versions of JBOSS AS(JBoss 7) also. 3) In existing ALBPM process definition we could see 65-70% of albpm:extensions and logic in PBL (ALBPM scripting), for which we are planning to do the following: a. Write Handlers in JAVA (to replace scripting part which is currently written using PBL) b. Use IDE (JDeveloper Studio) to create process definition file. I appreciate all your help. Thanks, Raja
