An automated report can look polished and still be difficult to move, hand off, or recover. Portability asks what can leave the system in a usable form. Ownership asks who controls the report, its data, credentials, refresh jobs, and transfer decisions. Compare both before committing to a platform, because an attractive dashboard does not answer either question.
Draw the dependency chain
List the report artifact, semantic model or dataset, original data sources, scheduled refresh, calculated fields, credentials, workspace, account, and delivery channel. Mark an owner and backup owner for each part. A report file is not a complete handoff if it opens only after reconnecting to an inaccessible workspace or credential. Conversely, a static export may preserve the visible result but lose filters, drill-down, calculations, and refresh behavior.
Test artifact portability
Ask the vendor for the exact downloadable format and then perform a real export. Microsoft's Power BI download documentation says reports may be downloaded as a `.pbix` file, with available modes including a copy with data or a live connection depending on the report and configuration. It also lists eligibility requirements and limitations, including role requirements and restrictions for some models, sources, and workspace arrangements. That makes “can be downloaded” a testable but conditional capability, not a promise that every report is self-contained.
Open the exported artifact in a clean test environment. Check whether visuals, measures, relationships, filters, themes, accessibility properties, and refresh settings survived. Record every dependency that still points to the vendor service. If the product offers only PDF or images, score it as presentation portability rather than editable-report portability.
Test data portability separately
Export the underlying and summarized data for representative visuals. Microsoft's Power BI data-export documentation describes permission-dependent export to Excel and explains that sensitivity-label protection can carry to exported files. Verify the fields, row limits, data types, time zone, filter state, and machine-readable format in your own environment. A spreadsheet export may preserve values without preserving calculations, lineage, or interactive behavior, so keep those categories separate in the scorecard.
Inspect account and workspace ownership
Record which account legally and operationally controls the workspace, billing, connectors, refresh credentials, sharing rules, and recovery methods. Prefer an organization-controlled account over a former employee's personal login. Test adding a second administrator and removing the original creator in a nonproduction copy. The report should continue to refresh, open, and distribute after that change. If ownership cannot be reassigned, document the migration procedure and likely interruption.
Google's Looker Studio exit guidance tells users to permanently delete or transfer all reports and data sources to another owner before leaving the service. That is a useful reminder to test both report transfer and data-source transfer; transferring the visible report alone may leave a hidden operational dependency.
Compare with an evidence matrix
Give each option a result for: editable artifact export, raw-data export, documented schema, calculation export, credential separation, second administrator, ownership transfer, offline opening, scheduled-refresh recreation, permission history, accessibility retention, and deletion process. Use “verified,” “conditional,” “not supported,” or “unknown.” Add the exact test date, subscription tier, and role used. Do not turn an untested marketing statement into a verified result.
Run a miniature exit drill
Build one small report containing a data connection, calculated field, filter, table, chart, and scheduled delivery. Export it, transfer it to another authorized account, reconnect it with replacement credentials, refresh it, and compare the values with the source. Then remove the original test account and repeat. Time each step and note which vendor features or paid roles are required. This bounded drill reveals operational lock-in more reliably than a feature checklist alone.
Make the decision reversible
Choose the option whose known limitations match the organization's recovery capacity. Keep an inventory of reports and sources, a regular data export where permitted, documented calculations, named primary and backup owners, and a periodic transfer test. If two products are close, prefer the one with a demonstrated exit route and fewer opaque dependencies. The winning choice is not necessarily the tool with the most export buttons; it is the one whose report, data, permissions, and operating knowledge can be recovered by the next authorized owner.
