IBM i migration · CDP4i / CDP4i-HA
Secure migration in under an hour
Move an IBM i partition from one Power server to another, with very limited production downtime and the option to roll back or postpone the project at any time — whether the partitions are on-premise or hosted.
- Under 1 h downtime
- Zero data loss
- Reversible at any time
- On-premise or cloud
Why secure migration
Two risks of classic migration, eliminated
The traditional method exposes you to a long service outage and to data loss. Our CDP4i and CDP4i-HA software removes both risks.
Classic migration: risk of data loss when reading the backup cartridge or during a roll-back.
0data loss
Secure replication before switchover: no data lost.
The process
Migration in 5 steps
From preparing the target partition to the switchover, each step is validated by the Client.
- 1
Target preparation
Creation of the target partition and handover of its characteristics to obtain the software keys.
- 2
Restore & tests
Production backup, restore of apps and data into the target, then Client validation.
- 3
Continuous replication
CDP4i then CDP4i-HA synchronise and replicate production to the target continuously.
- 4
Switchover
Production stop, replication finishes within minutes, then network and users switch over.
- 5
Production on target
Downtime limited to under an hour, with no data loss.
