Migration to Oracle Exadata
AvailableOn premiseCloud
Planning, migration and stabilisation of critical databases on Exadata, with the operation carrying on through the transition.
What is at stake
Migrating a critical database is the operation where a mistake has no cheap undo. On the other side there is a business system, a nightly integration and people who need to work on Monday.
How Master works
Master assesses first: what runs today, what it consumes, what depends on it. From that picture comes a migration plan with a window, a cutover order, a rollback test and an objective criterion to decide whether to go on or go back. A plan without a way back is not a plan.
During the cutover, the operation keeps happening. After it comes the part that usually gets forgotten: stabilising, tuning performance with real load and sustaining. Master stays for that phase, which is where the migration actually ends.
What it includes
- Assessment of the current environment and migration plan
- Database migration within a controlled window
- Stabilisation and performance tuning
- Post migration sustainment
The Master way
The technology is Oracle. Planning the cutover, going through the small hours and stabilising afterwards is Master work.
The technology belongs to the vendor. What Master puts on top of it is people who care, discipline with information, and respect for large operations.
- 01
People who care
A migration window is a long night for everyone, including the client team. Master agrees roles and timings beforehand, communicates in plain language throughout, and does not leave anyone finding out through monitoring what they should already have known.
- 02
Information security
Data leaves one place and enters another: it is the moment of greatest exposure for any database. A validated backup before the cutover, controlled transport and integrity checking on arrival are acceptance steps, not good intentions.
- 03
Respect for large operations
Master treats post migration performance as part of the scope. A new database that answers worse than the old one is an incomplete migration, and fixing that with real load takes time that has to be planned from the start.
