Document link migration
View Patent ↗Techniques and systems for migrating links in documents are described. For example, during a migration process, a first document may be selected to be migrated from a source document database. A determination may be made that the first document includes a link to a second document. The first document may be migrated to a target document database. The second document may be selected to be migrated from the source document database. The second document may be migrated to the target document database. The link in the first document may be finalized to include an address of the second document in the target document database.
1. A computer-implemented method, comprising:
selecting a first document to migrate from a source document database;
determining that the first document includes a link to a second document;
verifying that the link to the second document is a valid link, wherein verifying that the link to the second document is a valid link includes verifying that the link is not self-referencing;
selecting the second document to migrate from the source document database;
migrating, by a migration agent, the second document to the target document database;
modifying, by a link rewriting agent, the link in the first document to include an address of the second document in the target document database, wherein the link rewriting agent is configured to modify the link in the first document that references the second document while the migration agent is migrating the second document to the target document database;
determining that second document includes zero links; and
storing, in a link table, second link information associated with the zero links being included in the second document.
2. The computer-implemented method of claim 1 , further comprising:
migrating the first document to the target document database in parallel with selecting the second document to migrate from the source document database.
3. The computer-implemented method of claim 1 , further comprising:
updating, in a document table, an entry associated with the second document to indicate that the second document has been migrated to the target document database.
4. The computer-implemented method of claim 3 , further comprising:
modifying the link in the first document to include the address of the second document in the target document database based at least in part on determining that the second document has been migrated to the target document database.
5. The computer-implemented method of claim 1 , wherein, after migrating the second document to the target document database, the method further comprises:
indicating, in a link table, that the link in the first document has been finalized after modifying the link in the first document to include the address of the second document in the target document database.
6. The computer-implemented method of claim 1 , wherein migrating the second document to the target document database comprises converting the second document from a first format to a second format that is different from the first format.
7. One or more non-transitory computer-readable media, comprising instructions that are executable by one or more processors to perform operations comprising:
selecting a first document to migrate from a source document database;
determining one or more links in the first document including a link to a second document;
verifying that the link to the second document is a valid link, wherein verifying that the link to the second document is a valid link includes verifying that the link is not self-referencing;
selecting the second document to migrate from the source document database;
storing the second document in the target document database;
modifying the link in the first document to include a location of the second document in the target document database, wherein the link in the first document that references the second document is modified while the second document is being migrated to the target document database;
determining that second document includes zero links; and
storing, in a link table, second link information associated with the zero links being included in the second document.
8. The one or more non-transitory computer-readable media of claim 7 , the operations further comprising:
determining that the first document includes the link to the second document in parallel with selecting the second document to migrate from the source document database.
9. The one or more non-transitory computer-readable media of claim 7 , the operations further comprising:
updating, in a document table, an entry associated with the second document to indicate that the second document has been migrated after migrating the second document to the target document database.
10. The one or more non-transitory computer-readable media of claim 7 , the operations further comprising:
indicating, in a link table, that the link in the first document has been finalized after modifying the link in the first document to include the address of the second document in the target document database.
11. The one or more non-transitory computer-readable media of claim 7 , wherein:
the source document database includes at least one document in a first format; and
the target document database includes at least one document in a second format that is different from the first format.
12. A computing device, comprising:
one or more processors; and
one or more non-transitory computer-readable media storing instructions that are executable by the one or more processors to perform operations comprising:
selecting a first document to migrate from a source document database;
determining that the first document includes a link to a second document;
verifying that the link to the second document is a valid link, wherein verifying that the link to the second document is a valid link includes verifying that the link is not self-referencing;
selecting the second document to migrate from the source document database;
migrating the second document to the target document database;
modifying the link in the first document to include an address of the second document in the target document database, wherein the link in the first document that references the second document is modified while the second document is being migrated to the target document database;
determining that second document includes zero links; and
storing, in a link table, second link information associated with the zero links being included in the second document.
13. The computing device of claim 12 , wherein migrating the second document to the target document database comprises converting the second document from a first format to a second format.
14. The computing device of claim 12 , wherein the source document database includes at least one of a word processing document, a spreadsheet document, a presentation document, or an electronic mail (email) document.
15. The computing device of claim 12 , further comprising:
modifying the link in the first document to include the address of the second document in the target document database based at least in part on determining that the second document has been migrated to the target document database.
16. The computing device of claim 12 , wherein, after migrating the second document to the target document database, the operations further comprise:
indicating, in a link table, that the link in the first document has been finalized after modifying the link in the first document to include the address of the second document in the target document database.
17. The computing device of claim 12 , further comprising:
selecting a third document to migrate from the source document database;
migrating the third document to the target document database; and
modifying a link in the first document to include an address of the third document in the target document database.
18. The computing device of claim 17 , wherein the selecting, the migrating and the modifying are performed substantially in parallel.
