We are developing data migration programs to convert IMS to DB2
data. We have two methods. Wanted to Know which one takes less time and
the reason behind it ?
Method 1 :
Use the IMS unload utility and get the IMS database into a single
GSAM file. Write a program which reads this GSAM file and builds up the
DB2 load file.
Read the IMS database directly and build the DB2 load file.
