+=============================================================================
+Deprecation: #94902 - Deprecate lowerCamelCase options of EXT:impexp commands
+=============================================================================
+
+See :issue:`94902`
+
+Description
+===========
+
+The CLI commands :shell:`impexp:export` and :shell:`impexp:import` offered
+lowerCamelCased options, while the other TYPO3 Core commands offer lowercase
+options only. The lowercase option aliases were introduced in both commands and
+the lowerCamelCased options were marked as deprecated and will be removed in
+TYPO3 v12.
+
+
+Impact
+======
+
+If the CLI commands :shell:`impexp:export` or :shell:`impexp:import` are
+executed with lowerCamelCased options, a PHP :php:`E_USER_DEPRECATED` error is
+raised.
+
+
+Affected Installations
+======================
+
+Any TYPO3 installation using lowerCamelCased options with commands
+:shell:`impexp:export` or :shell:`impexp:import`.
+
+
+Migration
+=========
+
+Switch to the lower-cased option aliases:
+
+1. :shell:`impexp:export --includeRelated` => :shell:`impexp:export --include-related`
+2. :shell:`impexp:export --includeStatic` => :shell:`impexp:export --include-static`
+3. :shell:`impexp:export --excludeDisabledRecords` => :shell:`impexp:export --exclude-disabled-records`
+4. :shell:`impexp:export --excludeHtmlCss` => :shell:`impexp:export --exclude-html-css`
+5. :shell:`impexp:export --saveFilesOutsideExportFile` => :shell:`impexp:export --save-files-outside-export-file`
+6. :shell:`impexp:import --updateRecords` => :shell:`impexp:import --update-records`
+7. :shell:`impexp:import --ignorePid` => :shell:`impexp:import --ignore-pid`
+8. :shell:`impexp:import --forceUid` => :shell:`impexp:import --force-uid`
+9. :shell:`impexp:import --importMode` => :shell:`impexp:import --import-mode`
+10. :shell:`impexp:import --enableLog` => :shell:`impexp:import --enable-log`
