r/devopsjobs

send me resources if you have ?

I’m a sysadmin/devops-y person at a small manufacturing company, and we’re still on Microsoft Dynamics NAV (yep, classic Navision). This came up again after a fun 3 AM call last week because a NAV integration job died and blocked shipping.

Right now it’s a Frankenstein setup - on-prem NAV, a bunch of SQL jobs, some PowerShell scripts I hacked together, and manual “deployments” via RDP and copying files. No CI/CD, no infra-as-code, backups are half-automated. It works… until it really doesn’t.

I was googling around and found stuff like https://tigunia.com/services/navision-dynamics-nav/ and similar sites talking about upgrades, support, etc., but it’s hard to tell if we should pay specialists or just build more solid DevOps practices around what we already have. Maybe I’m looking at this the wrong way.

For people who’ve dealt with NAV (or other old ERPs): did you invest in automating/testing/monitoring around it, or did you push for a full upgrade/migration instead? Any war stories, tools, or patterns that actually helped keep this kind of legacy stack stable?

Independent contractor available for short-term or contract work (remote/global). I focus on production stability and fast fixes.

What I do

• Incident response / production debugging (MTTR reduction)

• Kubernetes reliability + rollout stabilization

• Observability + logging cleanup (Elastic/OpenSearch), cost + noise reduction

• Infra automation (Terraform, CI/CD) + runbooks/rollback

• Backend services & performance (Go/Python)

Recent outcomes

• IAM key rotation automation → ~95% reduction in security-related downtime

• Elastic ILM/shard tuning (~8TB) → ~20% storage reduction while maintaining latency SLOs

• Zero-downtime Filebeat → Elastic Fleet migration (20+ nodes)
