F5 BIG-IP Services
End-to-end TMOS lifecycle management for enterprise network infrastructure. From pre-upgrade assessment through post-upgrade validation — every engagement is executed with precision inside your change window.
TMOS Software & Code Upgrades
Full-lifecycle BIG-IP TMOS version migrations with boot location partitioning, UCS archive backups, CVE hotfix patching, and strict change-window execution.
Compatibility matrix review across v11.x through v17.x upgrade paths. UCS backup verification, boot slot inventory (HD1.1/HD1.2 volume partitioning), and iRule/iApp deprecation audit before any change window opens.
Target TMOS version staged to inactive boot slot and validated in isolation before any traffic impact. Rollback path confirmed and tested prior to cutover — no surprises during execution.
Emergency and scheduled CVE remediation with hotfix applicability assessment, patch staging to inactive slots, and post-patch validation. Includes EoSD milestone planning and emergency upgrade path execution.
Virtual server health checks, pool member status verification, SSL profile integrity, and traffic flow confirmation against pre-upgrade baselines. Change window does not close until all validation gates pass.
vCMP Matrix Staging & Tenant Architecture
vCMP host/guest OS version matrix management, slot provisioning, and next-gen rSeries/VELOS containerized tenant instance staging — without dropping traffic across virtualized clusters.
Detailed vCMP guest/host version matrix analysis to identify valid upgrade paths and sequencing requirements. Guest resource allocation, CPU pinning, and VLAN trunk assignments reviewed before any change window.
vCMP guest images staged and validated on host prior to promotion. Slot provisioning sequenced to maintain guest availability throughout the upgrade process, with per-guest traffic verification at each stage.
Next-gen containerized tenant instance provisioning on rSeries appliances and VELOS chassis. Tenant image deployment, network interface mapping, and TMOS-Next configuration validated prior to production cutover.
Host TMOS upgrades sequenced to maintain guest and tenant availability throughout the process. Traffic continuity verified at each stage — no unplanned guest restarts or tenant interruptions.
LTM, GTM / DNS & APM Configuration
Deep module architecture across Local Traffic Manager, Global Traffic Manager DNS/GSLB, and Access Policy Manager — with post-upgrade validation, SSL/TLS re-binding, and HA state synchronization.
Virtual server configuration review, pool member health monitor validation, persistence profile verification, and SSL offload profile integrity checks. Post-upgrade traffic flow confirmed against pre-upgrade baselines.
SSL/TLS client and server profile re-binding after TMOS upgrades. Cipher set updates for deprecated algorithms, certificate chain integrity verification, and OCSP/CRL responder connectivity confirmed.
Wide-IP health dependency mapping, DNS Listener configuration review, topology record validation, and GSLB pool configuration for multi-datacenter environments. BIG-IP DNS sync group health verified post-upgrade.
Access policy integrity verification post-upgrade, session variable mapping review, and AAA server connectivity confirmation. HA pair config-sync state and DSC group health verified before change window close.
iRules Refactoring & Optimization
Code auditing and refactoring legacy Tcl iRules for modern TMOS compatibility — identifying deprecated syntax, optimizing connection handling logic, and pre-validating rules against live production traffic profiles.
Systematic review of all iRules against target TMOS version release notes — identifying deprecated commands, removed events, changed Tcl behaviors, and incompatible iApp template versions.
Refactoring of inefficient Tcl patterns and connection handling logic. Removal of deprecated commands, modernization of rule logic for the current TMOS event model, and optimization of high-frequency rule execution paths.
Pre-validation of custom traffic inspection rules against live production traffic profiles. Layer 7 payload inspection logic reviewed for correctness and performance impact before go-live.
Pre- and post-upgrade traffic capture comparison to confirm iRule behavior is consistent. Regression testing against production traffic profiles — change window does not close until all rule behaviors are verified.
How an Engagement Works
Upgrade Readiness Assessment
We review your current BIG-IP environment — hardware platform, TMOS version, module configuration, and upgrade history — and produce a written readiness report with recommended upgrade path.
Change Window Planning
Detailed runbook developed for your specific environment. Every step sequenced, timed, and documented — including rollback procedures and go/no-go decision points.
Staged Pre-Work
Software staged to inactive boot slots, UCS backups verified, and pre-upgrade validation completed before the change window opens. No surprises during execution.
Change Window Execution
Upgrade executed per runbook with real-time traffic monitoring. Failover testing, post-upgrade validation, and sign-off completed before change window closes.
Plan Your Next Upgrade Cycle
Whether you're facing an EoSD milestone, a CVE remediation deadline, or a platform consolidation — we bring the expertise to execute it cleanly.
