What would be the best practice to convert existing DDS physical table to a temporal table using Aldon?

The following columns need to be added to the physical table:

ADD COLUMN TEMPORAL_ROW_START TIMESTAMP(12) IMPLICITLY HIDDEN NOT NULL GENERATED ALWAYS AS ROW BEGIN
ADD COLUMN TEMPORAL_ROW_END TIMESTAMP(12) IMPLICITLY HIDDEN NOT NULL GENERATED ALWAYS AS ROW END
ADD COLUMN TEMPORAL_ROW_TRANS TIMESTAMP(12) IMPLICITLY HIDDEN NOT NULL GENERATED ALWAYS AS TRANSACTION START ID
ADD COLUMN TEMPORAL_audit_user VARCHAR(128) GENERATED ALWAYS AS (SESSION_USER)
ADD COLUMN TEMPORAL_audit_op CHAR(1) GENERATED ALWAYS AS (DATA CHANGE OPERATION)
ADD PERIOD SYSTEM_TIME(TEMPORAL_ROW_START, TEMPORAL_ROW_END

Also, a history table needs to created and associated with the physical table:

ADD VERSIONING USE HISTORY TABLE libray.tablename_history ON DELETE ADD EXTRA ROW

Ramiro, I think you've posted this question in two different threads?  Posting my last comments/summary from the other posting ("How to change physical file (DDS) to become a temporal table using Aldon?").  
Best,

...detail from our L3 for LMi below.  Pls run it through support if this doesn't get you past the finish line.

...minimum LMi 8.5 and V7R3. 
first add history *TABLE.  
then checkout and convert *FILE to *TABLE with option 16.  
then option 16 again to convert *TABLE to temporal table...  
there are other details but seems they lend themselves more to a support call...  
things like moving source from QDDSSRC to QSQLSRC (if they choose to do so), change member source type from PF to SQL, etc...
