Can these reports move safely?
See which SSRS reports, datasets, data sources, parameters, and RDL patterns are straightforward, risky, stale, or better retained for now.
Microsoft BI Modernization Assessment
Untangle your legacy BI estate before you modernize it.
TangleMap turns SSRS reports, SQL Agent jobs, SSIS packages, SSAS Tabular models, and SQL Server dependencies into structured modernization evidence so teams can see what exists, understand what is uncertain, and choose a defensible next step.

The planning gap
Modernization stalls when the estate is unclear.
Interviews, screenshots, scripts, and spreadsheets can leave teams unsure which assets exist, which dependencies matter, what is still used, and where access gaps reduce confidence. TangleMap turns those questions into a structured assessment path.
How tangled is the ETL estate?
Review SSISDB packages, environments, parameters, SQL Agent orchestration, execution history, and coupling before estimating migration effort.
What depends on what?
Trace report, job, package, semantic-model, and SQL metadata evidence back to databases, procedures, views, and tables where detectable.
Which assets still matter?
Use execution history, schedules, enabled state, centrality, and dependencies to separate critical assets from stale or unclear ones.
What path is defensible?
Support retain-and-investigate, phased modernization, and priority planning decisions without assuming the destination up front.
What we assess
Focused on the Microsoft BI estate that usually blocks planning.
The first assessment scope is intentionally narrow: legacy SQL Server BI systems where reports, jobs, packages, models, and SQL objects often hide the real modernization risk.
See the full assessment scopeReporting layer
Reports, shared datasets, data sources, folders, parameters, RDL patterns, and execution signals where available.
ETL and orchestration
Packages, projects, environments, parameters, jobs, steps, schedules, history, and operational coupling.
Data and semantic layer
Databases, schemas, tables, views, procedures, tabular models, partitions, measures, and source queries.
What TangleMap does
From local collection to a reviewable assessment.
The collector runs in the client environment, creates an encrypted evidence bundle, and feeds consultant-facing review tools for the inventory, dependencies, caveats, scoring, and recommendations needed before planning implementation work. This is the short version; the process page explains the steps in more detail.
Read how the assessment flow worksCollection
Collect local evidence
Run inside the client environment and gather metadata, raw artifacts, warnings, and coverage signals.Evidence
Build the evidence model
Normalize assets and relationships across reports, jobs, packages, models, and SQL objects.Complexity
Score the hard parts
Expose complexity drivers with confidence and coverage caveats instead of false precision.Findings
Review what matters
Separate critical, stale, risky, ambiguous, and incomplete areas for assessment discussion.Roadmap inputs
Shape next decisions
Use the assessment readout to support pilot scope, modernization paths, roadmap options, and partner planning.What the output looks like
Deliverables built for assessment readout.
Outputs are built for consultant assessment review and planning. They provide evidence, caveats, and scoring signals that still need interpretation before roadmap or implementation recommendations are final.
See sample output surfacesEstate inventory
Source systems, assets, schedules, jobs, reports, packages, models, and selected raw artifacts where useful.
Dependency map
Direct, parsed, and inferred relationships with evidence type and confidence instead of hidden certainty.
Coverage report
Partial scans, inaccessible surfaces, unsupported patterns, and reduced-confidence findings stay visible.
Complexity scorecard
1-5 migration complexity signals with explainable drivers rather than black-box precision.
Modernization recommendation
Target-neutral retain-and-investigate, phased modernization, or priority-planning guidance for architecture review.
Readout pack
CSV exports and printable summaries for consultant review, stakeholder discussion, and follow-up planning.
What happens after the output
The readout becomes a planning conversation.
TangleMap does not replace architecture judgment. The output gives the team a shared evidence base so consulting, delivery, and business stakeholders can decide what is trusted, what needs investigation, and what can move into a roadmap.
Credibility
Evidence-backed, not overconfident.
TangleMap produces dependency evidence, not guaranteed complete lineage. Relationships may come from direct metadata, parsed definitions, command text, raw artifacts, or heuristic inference.
Scope
Designed for planning, not automated conversion.
The output supports inventory review, complexity scoring, coverage gaps, confidence caveats, rationalization candidates, and roadmap discussion. Consultant architecture review remains part of the assessment.
Next step
Start with the assessment question.
If the estate is hard to document, hard to scope, or hard to modernize with confidence, start by turning it into structured evidence.
