End-of-life Elasticsearch migration
- SSPL risk eliminated
- 6-week dual-write window
- Rollback rehearsed before cutover
Australia · Security & platform engineering
For CISOs, platform leads, and risk teams under a dated clock
Migration deadlines, regulator evidence, and data in Sydney or Melbourne
Elasticsearch 8.x EOL is dated. Essential Eight ML2 needs evidence, not slides. CPS 234 expects systematic testing your auditors can follow. We deliver all three — with production proof from regulated estates.

Four places to begin
Each tile is a commercial pillar with deep guides, interactive tools, and case proof. Pick the problem closest to your deadline.
Australian delivery architecture
Data residency designed end to end
Australian workloads can stay in ap-southeast-2 (Sydney) or ap-southeast-4 (Melbourne) end to end. Data does not leave the country.
Data plane
Primary storage, replicas, snapshots, queues and DR in ap-southeast-2 or ap-southeast-4.
Engineering access
Controlled administration paths, MFA, session logging, and limits on bulk export.
Privacy review
APP 8 cross-border disclosure assessed where logs may contain personal information.
Measured outcomes
Migration and assurance work with numbers attached
Real programmes from regulated estates — not hypothetical benchmarks.

Elasticsearch EOL hub →Common questions
Australia delivery: common questions
For platform, security and compliance leads scoping migration or assurance work.
Where is AiRAT based, and how do you work with Australian clients?
AiRAT is headquartered in Jaipur, India, with AEST/AEDT business-hours overlap. Engagements use controlled remote engineering access and architectures that keep production data in Australian Regions when required.
Can production data stay in Australia during a migration?
Yes. Source and target clusters, snapshots, replay queues, migration workers and DR can be constrained to ap-southeast-2 (Sydney) and ap-southeast-4 (Melbourne) when the design covers observability exports and support paths end to end.
What Essential Eight services does AiRAT provide?
Gap assessments, evidence-quality mapping, uplift engineering and retest packs mapped to ASD's current ML2 guidance, including tracking the 2026 Essentials transition. IRAP assessments are out of scope.
What CPS 234 work does AiRAT deliver?
Technical control testing, penetration testing, remediation engineering and evidence packs inside a systematic testing programme. Statutory audit and IRAP assurance remain with your appointed functions.
Should I message you or book a call?
Either works. Use the contact form to send your context asynchronously: stack versions, regulator deadline, residency requirements. Book a call if you prefer to talk through scope live. Both routes reach the same engineering team.
