Delta migration for objects scanned with previous verison of migration-center is **not supported**.\ This only applies when scanning from Exchange Online, due to switching the Exchange scanner from the deprecated EWS API to Microsoft Graph, the unique identifiers for each email have a slightly different format. As a result, previously scanned emails can no longer be recognized and will be treated as new objects. {% hint style="danger" %} Running delta scan with the new version over scans from the previous version **can result in duplicate objects scanned**. {% endhint %} Our recommendation is to finish migrations for any mailboxes that are in progress and for which no delta scans will be needed in the future, and only then upgrade migration-center and start scans of new mailboxes, to avoid duplication. ### Features & Enhancements * NEW Doxis Importer: * Doxis repository authentication (#81906) * Import documents content and metadata (#81907) * Import documents versions (#81955) * Check content integrity on import (#81908) * Delta migration of documents (#81911) * Import E-Files (#81909) * Add multithreading capabilities (#81910) * All components: * Add support for encrypted connection to Oracle with wallet (#82699) * Integration with migration-center Classify (#80511) * Configure migration-center classify connection (#81810) * The classification step is available in the migset configuration when the classify connection was configured (#81811) * Configure migset classification (#81812) * Monitor the classification progress in the migset classification tab (#81849) * Import the classification results in migration-center (#81902) * Documentum and DocumentumAuditTrails scanners: * Change audit trail order to Newest to Oldest in pdf (#82744) * Exchange Scanner: * Replace EWS with Microsoft Graph (#82204) * OpenText Importer: * Add proxy support (#81927) * Set multilingual name and description on Business Workspaces (#82093) * Set ACLs via REST API (#81936) * Set Multilingual metadata via REST (#82501) * Veeva Importers: * Add extra logging for attribute mapping (#81961) * WebClient * Remain on the same page when switching projects (#80963) ### Fixes * Database: * Box folder\_path is limited to 255 during association (#81884) * Debug value for tr. function GetInternalAttribute('Content\_location') returns wrong attribute value on Oracle (#81813) * Generate rules doesn't work if migset object selection was manually stopped (#82560) * WebClient: * Scanner/Importer/Migset Selection is not always visible on scheduler (#81714) * Moving items from one table to another with double click requires moving the mouse (#82187) * Redirect to login on refresh page even if refresh token not expired (#80303) * Selection not being kept after deleting Item on mapping lists and object types (#75881) * Global Object Search button is active when no search parameters are set (#65531) * CTRL+A does not work on View Value dialog (#61676) * Documentum Audit Trail, Veeva, OpenText Scanners: * PDF generation convert some unicode characters (#81871) * PDF Generation fails when audittrail attributes contain unicode control characters (#81794) * DocumentuAuditTrail scanner: * Documentum Audit Trail Scanner continues generating PDFs after being stopped from the web client (#82022) * OpenText importer: * Opentext Importer throws NPE when importing documents with restBaseUrl parameter empty (#82107) * SharePoint Online scanner: * Add support for content files larger than 2GB for SPO Scanner (#81888) * Timeout set in config file not used properly in mc-rest-client (#82065) * SharePoint Online importer: * Authentication is not renewed after token expires (#82542) * Veeva importer: * Veeva importer cache does not fetch all users (#82121) * Veeva importer processes virtual document relations for migsets targeting Documents (#82692) ### Known Issues and Limitations * CSV / Excel scanner: * CSV file with non-utf8 encoding fails to scan (#82569) * OpenText importer: * Importer allows importing nested ACL permission without parent permissions (#82319) * Doxis Importer: * Errors when setting different database on different versions while E-File linking is also being done (#82804) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.migration-center.com/release-notes.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
