OSSEVA FOR MONGODB
MongoDB support for self-managed 4.2 to 6.0, patched past end of life.
OSSeva provides MongoDB support for self-managed Community Server, including patched builds for 4.2, 4.4, 5.0 and 6.0 after MongoDB's end of life, and planned upgrades to the supported 7.0, 8.0 and 9.0 releases. Security coverage is committed under contract, and the route through each featureCompatibilityVersion step is mapped before it starts.

Why now
MongoDB 5.0 and later need AVX
On x86_64, MongoDB 5.0 and later require the AVX instruction set. Older hardware and some hypervisor CPU models, such as the generic kvm64 profile, do not expose AVX, so mongod typically crashes on start with an illegal instruction error. Estates on that hardware are held on 4.4 until the platform changes.
Upgrades go one major version at a time
MongoDB requires each major version to be installed in turn, with featureCompatibilityVersion raised at every step. Moving from 4.4 to 7.0 means three full upgrades of every replica set and sharded cluster, each with its own driver compatibility checks.
Post-EOL fixes are discretionary
MongoDB's support policy carries no obligation to support versions past end of life. It has shipped some post-EOL releases, such as the December 2025 fixes for CVE-2025-14847, but 4.2 and earlier received no fix for that known-exploited flaw at all. Estates that need a commitment, not a hope, need someone contracted to deliver it.

How it installs
OSSeva artifacts arrive via your existing package infrastructure. Pull the patched version the same way you pull upstream today — just from the OSSeva registry.
# MongoDB 5.0+ on x86_64 needs AVX. Empty output means this host cannot run it.
grep -o -m1 '\bavx\b' /proc/cpuinfo

MongoDB's commercial support covers its supported releases. For self-managed Community Server estates held on end-of-life versions by hardware, drivers or certification, OSSeva patches the version you run while the upgrade is planned.

Frequently asked questions
Why does MongoDB 5.0 fail with an illegal instruction error?
MongoDB 5.0 and later require the AVX instruction set on x86_64. If the CPU, or the CPU model exposed by the hypervisor, does not provide AVX, mongod crashes on start. The official Docker image prints a warning that MongoDB 5.0+ requires a CPU with AVX support. Run it on AVX-capable hardware, expose AVX from the hypervisor, or stay on 4.4 with extended support.
Can I upgrade MongoDB 4.4 directly to 7.0?
No. MongoDB upgrades go through each major release in turn: 4.4 to 5.0, 5.0 to 6.0, then 6.0 to 7.0, raising featureCompatibilityVersion after each step.
Does OSSeva support MongoDB Atlas?
No. Atlas is MongoDB's managed service and MongoDB patches it. OSSeva supports self-managed MongoDB Community Server.
How is licensing handled?
MongoDB Community Server is distributed under the Server Side Public License. OSSeva provides patched builds and support for your own self-managed use; running MongoDB as a service for third parties has separate SSPL obligations that apply whoever supports it.
Who provides MongoDB support besides MongoDB?
MongoDB sells commercial support for its supported releases through MongoDB Enterprise Advanced, and patches Atlas, its managed service, itself. Independent support and consulting companies cover self-managed Community Server deployments. OSSeva is one of the independent providers: one contract that covers MongoDB beside the rest of your data stack, end-of-life versions 4.2 to 6.0 included, on your own servers, including hosts without AVX.
Does OSSeva support current MongoDB versions or only end-of-life ones?
Both. OSSeva Patch ships security fixes for 4.2, 4.4, 5.0 and 6.0, which MongoDB has no obligation to fix after end of life. Versions 7.0, 8.0 and 9.0 receive upstream fixes, and the higher tiers take you there: Assure adds a featureCompatibilityVersion upgrade plan and driver audit, and Operate executes major-version upgrades with 24/7 replica set and cluster monitoring.
How is OSSeva MongoDB support priced?
OSSeva MongoDB support is priced per replica set or cluster, and the tier you choose, Patch, Assure or Operate, sets how much of the work OSSeva takes on. The database support cost calculator at /tools/database-support-cost-calculator estimates what your current support arrangements cost, using your own figures. Book a discovery call for a quote.
