Techieism Project Spotlight
🏆 Our WorkSAP on a 20-Year-Old Server That Can't Be Upgraded — Moved to a Fully Backed-Up VM. ₹0 Downtime Risk.
A client's mission-critical SAP installation was running on a physical Windows Server 2003 machine. The SAP version itself could not be upgraded, and Server 2003 has had no vendor patches or hardware replacement path for over a decade. Every day the client operated, they carried the risk that a single disk or motherboard failure would take the entire system down with no way to recover it — right in the middle of planning their new ERP implementation.
Techieism built a new virtual environment and migrated the entire physical server into a VM — same OS, same licence, same SAP installation, completely unchanged from the application's point of view. The VM now runs on modern, redundant virtualisation infrastructure with automated daily backups. If the ageing Server 2003 instance itself ever gets corrupted, it's restored from backup in minutes — no dependency on failing physical hardware ever again. The client is now completely free of hardware failure risk, and their new ERP rollout is proceeding exactly on timeline, without the pressure of an emergency migration.
Past Projects
📚 PortfolioOEM Firewall Licence Limitations — Replaced with OPNsense, Samba AD, RADIUS & OpenVPN. ₹0 per Year.
The client's OEM commercial firewall had reached its licence limits, restricting users, connections, and features. Techieism replaced it with OPNsense open-source firewall, and layered on Samba Active Directory, RADIUS network authentication, and OpenVPN remote access — a fully integrated stack with zero annual licence cost and more capability than the commercial product it replaced.
Enquire About This Solution →Business Email Compromise, Contained. Attacker Evicted from M365 — Full Forensics.
A client received email from a known contact whose M365 account was compromised via AiTM phishing. Techieism traced the attack through the Unified Audit Log, revoked sessions, removed inbox rules, reset credentials with MFA, and hardened the tenant with Conditional Access policies. Attacker fully evicted, zero data loss.
Enquire About This Solution →~2TB of SharePoint Data. Two Companies. Zero Data Loss. Zero Paid Migration Tools.
A corporate restructuring required migrating nearly 2TB of SharePoint data across Microsoft 365 tenants. Techieism engineered the entire migration using PowerShell scripting alone — no third-party tool licences, no data loss, full permission mapping, and incremental sync. Every document arrived intact.
Enquire About This Solution →One Server. Four VMs. One Windows Licence Instead of Four. No RAID Controller.
A CA firm needed file server, Active Directory, Tally ERP, and Winman — the conventional approach meant four Windows Server licences, CAL costs, and a hardware RAID controller. Techieism built the entire setup on one machine using Proxmox VE, with Linux VMs for AD and file server (free) and one Windows Server VM for both Tally and Winman. ZFS RAID replaced the hardware controller entirely.
Enquire About This Solution →Four Offices. One Domain. Zero Extra Windows Server Licences.
A multi-office company needed centralised user authentication across all locations. We deployed 4 Samba Active Directory Domain Controllers — one per office — with automatic cross-site replication, single sign-on for all staff, and Group Policy enforcement. Any employee logs in with one account at any office. Built entirely on Linux: no Windows Server licence cost.
Enquire About This Solution →All Offices Connected — No MPLS. No VPN Servers. No Costly Routers.
A multi-office organisation was spending heavily on MPLS leased lines and VPN hardware. We replaced the entire setup with OPNsense open-source firewalls at each site, a self-hosted Headscale mesh coordination server, and WireGuard encrypted tunnels between all locations. Every office connects securely to every other — servers, printers, internal apps — as if on one LAN. Remote staff connect to the same mesh. New offices added in minutes.
