Define what must survive the move
A note migration is more than transferring text. You may rely on attachments, internal links, dates, tags, comments or the order of a notebook. Decide which of these are essential before comparing import buttons. A tool can support the file format you have while still losing part of the structure that makes the notes useful. Write a short acceptance list in ordinary language, such as “each research note keeps its source link and attached PDF.”
Separate essential content from preferences you can rebuild. Losing a custom sidebar arrangement may be inconvenient. Losing the connection between a note and its evidence may be unacceptable. This distinction keeps the migration focused. It also prevents you from rejecting a suitable tool because it does not reproduce every cosmetic detail. The goal is to preserve the work and its meaning, not necessarily to make the new app look exactly like the old one.
Choose a deliberately difficult sample
Pick a small set of notes that represents the variety of your collection. Include plain text, a long note, a table, an image, a PDF attachment, an internal link and a note with unusual characters in its title. If you use comments or collaborative ownership, include those too. A sample of only short text notes gives false confidence because it avoids the parts most likely to behave differently.
Create a list of the sample items and what you expect to find after import. This list is your comparison record. Keep the original sample unchanged and export a separate copy. If the export offers several formats, test the one that preserves the information you care about rather than choosing the smallest download. A migration is easier to reason about when you can compare the source, exported files and imported result as three distinct stages instead of treating the process as one opaque action.
Read the importer limits before uploading
Import support is specific to the destination and source. Notion's official import documentation, for example, lists supported file types and explains that some source-specific elements do not transfer. Its Google Docs importer documentation says suggestions do not import and comments from other users are represented differently. These details matter if a note collection includes unresolved editorial discussion. Importing the final text alone may not preserve the work still needed to approve it.
Use the relevant documentation for your exact route rather than general claims that an app can import notes. Check whether the feature is available on your platform and whether there are limits on batch size or supported content. If the documentation leaves a point unclear, mark it for the sample test. Do not infer that an import preserves permissions merely because it preserves page titles. Content transfer and access transfer are separate questions, and the second can have consequences for other people.
Inspect meaning as well as appearance
After importing the sample, open each item and compare it with the original. Check whether paragraphs, lists and tables still communicate the same information. A table may look acceptable while a merged cell has shifted a label to the wrong value. An internal link may appear as blue text while pointing to the old service. A PDF may be shown as a link that works only while your old account remains active.
Search for a distinctive phrase and open an attachment from the new app. Follow links in both directions where your workflow depends on them. Check dates and tags if you use them to find notes. Record failures in a small issue list with a decision: fix before the full move, rebuild afterward or accept as a known loss. This makes the tradeoff explicit. It is better than vaguely feeling that the import “mostly worked” and discovering the missing detail months later.
Separate copying from switching
Once the sample passes, export the full collection and retain the original export in a safe location. Import into a clearly named destination area. Avoid editing the same notes in both apps during the transition unless you have a deliberate reconciliation plan. Two active copies quickly diverge, and a later merge can be more difficult than the original migration. Choose a switch date after the main checks, then tell collaborators which location is authoritative.
Do not delete the old collection immediately. Keep it available for a defined review period if your account terms and storage situation allow. A retained source gives you a way to recover an overlooked attachment or check an ambiguous conversion. Make the old workspace visibly read-only or archived where possible so that people do not continue updating it by habit. The transition should reduce uncertainty about where to work, not create a permanent split between two competing versions.
Verify portability in the destination
Before declaring success, export a few imported notes from the new app. This reveals whether the move has placed your information into a system you can leave again. You do not need perfect round-trip formatting for every use case, but you should understand the exit route. A readable archive with attachments may be enough for personal notes. A structured team knowledge base may need a more detailed recovery plan.
Finish with a migration record: what moved, when, from which source, which format was used and which limitations remain. Link to the sample checklist and the retained export. This record is especially valuable if someone else inherits the workspace. A careful migration does not require checking every character manually, but it does require testing the features that give the collection its value. The work is complete when the notes are usable, their dependencies are understood and the team knows where the authoritative copy now lives.
