Solaris
Solaris administration and evolution on SPARC and x86 where appropriate.
- Installation and upgrades
- Zones and services
- Storage and multipath
- Solaris Cluster integration
Enterprise operating systems integrated with the platform.
We work with Solaris, Linux, AIX, HP-UX and Windows across installation, configuration, upgrades and migration while keeping hardware, storage, network, applications and availability visible.

Platforms
Multi-platform experience for heterogeneous environments.
Version decisions are made with application dependencies, agents, filesystems, drivers and vendor support in view.
Linux
Enterprise Linux for databases, virtualization and infrastructure services.
- Kernel and packages
- LVM/XFS
- Storage integration
- Clustering and virtualization
Aix
AIX on IBM Power integrated with virtualization, storage and high availability.
- AIX and PowerVM
- Logical volume management
- SAN and multipath
- PowerHA / HACMP
Hp-ux and windows
Existing platforms that require continuity, upgrades or controlled transition.
- Version inventory
- Application compatibility
- Service migration
- Infrastructure integration
Implementation
Build a supported and repeatable platform.
Installation includes the surrounding services required to operate the system.
Platform baseline
Establish supported versions, packages, services and configuration.
- OS baseline
- Time/DNS
- Users and access
- Storage mounts
Infrastructure integration
Validate network, storage, monitoring and backup agents.
- Network
- Multipath
- Monitoring
- Backup integration
Upgrades
An operating-system upgrade is dependency management.
We identify what can break, what must remain compatible and how the platform will be validated after the change.
Readiness
Inventory versions, packages, services and application dependencies.
- Support matrix
- Drivers
- Agents
- Application prerequisites
Execution
Run the upgrade with checkpoints and a recovery plan.
- Change plan
- Backups
- Validation points
- Rollback criteria
Migration
Transition services without losing their context.
Operating-system migration includes data, service definitions, network identity and operational procedures.
Migration planning
Define source, target, dependencies and cutover sequence.
- Inventory
- Target build
- Data movement
- Cutover
Post-migration validation
Confirm services, connectivity, storage and application behavior.
- Service checks
- Network
- Storage
- Performance baseline
Operating System Pre-Flight
Upgrading the operating system means validating a dependency chain.
Before changing versions we review what boots, what mounts, what connects, which agents intervene and which applications depend on each service.
Version and patches
We define source, target and support constraints.
- Current release
- Patch level
- Repositories
- Kernel compatibility
Boot and filesystems
The change must preserve the boot path and data access.
- Bootloader
- LVM / filesystem
- Multipath
- Mounts and permissions
Agents and applications
Backup, monitoring, clustering and middleware can constrain the upgrade.
- Agents
- Services
- Libraries
- Application dependencies
Rollback and validation
The change window includes how to return and how to prove the service is healthy.
- Backup / snapshot
- Rollback
- Functional tests
- Evidence

A clear technical path reduces the risk of discovering incompatibilities during the change window.
