- [IBM i End-of-Life Decisions Are Simpler Than They Look](https://source-data.com/ibm-i-end-of-life-decisions-are-simpler-than-they-look/): When an IBM i version reaches end-of-life, security patches stop and the decision tree gets complicated fast. Here is how to evaluate ISV transfer fees, extended support, and cloud hosting before the deadline forces your hand.
- [Comparing the Three IBM i High Availability Architectures](https://source-data.com/three-ibm-i-high-availability-architectures-and-how-to-choos/): Three IBM i high availability architectures carry fundamentally different cost, bandwidth, and recovery tradeoffs. This field guide from Source Data Products helps mid-market IT leaders choose the right fit for their environment, risk tolerance, and operational model.
- [Your IBM i Software May Hold Competitive Advantages Worth Keeping](https://source-data.com/ibm-i-cloud-migration-software-competitive-asset/): Most IBM i migration decisions focus on the cost of moving. The more important question is what it costs to lose what your current software already knows. Cloud400 hosting preserves decades of competitive logic while solving the real infrastructure problems facing mid-market organizations.
- [IBM i Security Risks May Already Be Inside Your Network](https://source-data.com/ibm-i-security-audit-insider-threats/): IBM i security failures rarely arrive from outside the network. Orphaned profiles, copied permissions, and unrevoked consultant access create invisible exposure that standard compliance audits miss entirely. Here is what a genuine IBM i security audit uncovers and what it costs to fix.
- [Consider IBM i Right-Sizing With Cloud Hosting Before Buying Power11](https://source-data.com/power-11-ibm-i-right-sizing-cloud-lpar/): The Power 11 S1112 is technically impressive, but most mid-market IBM i shops run on a fraction of its capacity. Before committing to new iron, see how IBM i right-sizing with cloud LPARs compares on a five-year cost basis.
- [Most IBM i Hosting Proposals Don't Show What Matters Most](https://source-data.com/ibm-i-hosting-infrastructure-questions-providers-avoid/): IBM i hosting proposals rarely disclose what runs underneath: switch quality, storage tier, carrier diversity, or engineer caliber. These are the infrastructure questions every IT director and CIO should demand answers to before signing any hosting agreement.
- [ISV Transfer Fees That Stop IBM i Cloud Migrations Cold](https://source-data.com/isv-transfer-fees-that-stop-ibm-i-cloud-migrations-cold/): ISV software transfer fees are one of the most predictable obstacles in IBM i cloud migration. Learn the three questions to ask your vendor before a single hour of planning begins, and how to keep a high fee from killing a project that was otherwise ready to move.
- [IBM i Hosting Expertise Separates Right-Sizing From Guesswork](https://source-data.com/ibm-i-hosting-expertise-closes-the-right-sizing-gap/): Most IBM i hosting conversations start with specs and end with inflated monthly costs. The practitioners who ask about actual workload throughput first routinely produce 30 to 70 percent in hosting savings. Here is what IBM i hosting expertise actually delivers in practice.
- [IBM i V5R3 to V7.5 in 30 Days for Under $3,000](https://source-data.com/ibm-i-v5r3-migration-to-v75-for-under-3000/): The standard IBM i upgrade path from V5R3 to V7.5 costs around $15,000 and steps through multiple releases. One Washington DC organization completed the migration in 30 days for under $3,000. Here is how the right expertise changes the math.
- [Cut Hosting Costs With IBM i LPAR Right-Sizing](https://source-data.com/ibm-i-lpar-right-sizing-cuts-hosting-costs-30-to-70-percent/): IBM Power servers ship with far more capacity than most mid-market workloads ever consume. A genuine IBM i LPAR right-sizing assessment can reduce hosting costs by 30 to 70 percent before you sign your next contract, and Source Data proves it with a 60-day trial.
- [IBM i DR Test Failure Is the First Step to Recovery Readiness](https://source-data.com/ibm-i-dr-test-failure-is-the-process-working-correctly/): Most IBM i disaster recovery solutions sit untested for years. The first IBM i DR test almost always finds something. Here is what a failed test surfaces, why it is part of the process, and how to build a recovery plan that holds when it matters most.

- [IBM i Total Cost of Ownership Changed When Perpetual Licensing Ended](https://source-data.com/ibm-i-total-cost-of-ownership-after-perpetual-licensing-ends/): IBM's 2025 elimination of perpetual software licensing changed the buy-versus-host calculation for IBM i shops. A new entry-level Power server now represents an $80,000 to $100,000 five-year commitment. Here is what the current IBM i total cost of ownership math actually looks like.
