Impact is on time |
Risk due to load balancers being out of support and storage out of support from end of 2022 |

We will treat changes as a minor change as regards reporting to CAB

We will move servers as-is and re-assess and re-configure (e.g. move to stretch cluster) once migrations are complete

|We will migrate a 'large chunk as possible' as our first migration and base our estimates for capacity and elasped time based on this We will define non-production services as big as possible, of services and owners close to ITI, to track VM capacity and allocation, and how long it takes to move e.g. 50VM = 10TB & RAM & CPU -> and it took so long - we can then extrapolate
|
14/11/22 | ASSUMPTION is that the migration of test services will reflect the production migration | |||||
| We will aim to prepare for the load balancer migration by end of 2022 with some non-production migrations if we can - production migrations are not a priority vis-a-vis the VM migrations and will be progressed in 2023 | Sponsor, Technical Lead | 14/11/22 | |||||
| Reboot - based on length of time since last reboot (typically more than 2 months) | Sponsor, Technical Lead | 14/11/22 | |||||
| Change of Scope - this project will increase scope to include the Micro-Segmentation work in the procurement contract with support from Xtravirt | Sponsor, Technical Lead | 5/12/22 | |||||
| The physical decommissioning of the servers will not be part of this project | Sponsor | 30/1/22 | |||||
