I have a scenario where i want to migrate from AS/400 Model 810 running V5R3 to a new Power 7 machine with V7R1. I went through IBM documentation and deciding on approach to be followed.
First approach is to install IBM i 7.1 on new system and perform data migration from existing V5R3 system using data migration steps. I'll run ANZOBJCVN tool prior to migration.
Second approach which IBM highly recommends is to upgrade source system from V5R3 to V5R4 or V6R1 and then perform data migration to new system with V7R1.
In third approach i can migrate source system data with V5R3 to new system with V6R1 and then upgrade IBM i OS to V7R1 on the target system.
I need suggestion which option would be best among these and what other precaution i need to take for this process. I have to migrate 4 LPARS on current 810 model to new system. I am assuming this activity will take around 2-3 months including planning, preparation, implementation, testing and hand over. Please suggest.
Software/Hardware used: AS/400 Model 810. IBM Power System 7
