Code Review

Scope reviewed: config/routing/build-affecting changes only (per instructions, documentation content and style were not reviewed). This PR removes Directory Manager 11.0 (999 files: the docs/directorymanager/11.0/ tree, static/images/directorymanager/11.0/, sidebars/directorymanager/11.0.js, and a 6-line edit to src/config/products.js). No workflow or script files were changed.

No blocking issues found. The removal is clean and consistent:

• src/config/products.js — Only the 11.0 version block is removed. It was isLatest: false, and 11.1 remains isLatest: true with defaultVersion: "11.1", so there is no dangling latest/default reference.
• sidebars/directorymanager/11.0.js — Deleted; 11.1.js remains and is the only sidebar referenced by products.js.
• Redirects (docusaurus.config.js client-redirects) — Fully derived from products.js / getLatestVersionUrlMap(); nothing is hardcoded to 11.0. Directory Manager still qualifies for a base-to-latest redirect (/docs/directorymanager to /docs/directorymanager/11_1), so routing stays valid.
• Images — All 11.0 images are removed, and no surviving file references images/directorymanager/11.0. No cross-product image sharing was broken.
• Build integrity — With onBrokenLinks: "throw", I checked for internal links to deleted 11.0 pages/images. None found in retained files, so the build should not break on broken links.

Minor (non-blocking, does not break the build):

Three retained files still contain outbound links to now-removed directorymanager/11.0 URLs. These are absolute external URLs (https://docs.netwrix.com/..., https://releases.netwrix.com/...), which Docusaurus does not validate against onBrokenLinks, so they will not fail the build — but they will become dead links after deploy:

• docs/directorymanager/11.1/admincenter/service/securityservice/signkeyutility.md line 34 (releases.netwrix.com Signing-Key-Utility 11.0 zip)
• docs/kb/directorymanager/configuration-and-integration/how-to-add-message-approvers-in-group-properties-in-groupid-portal.md line 99 (.../directorymanager/11_0/signin/service/mobileservice/design/objectproperties)
• docs/kb/directorymanager/reporting-export-and-data-management/best-practices-for-controlling-changes-to-group-membership.md lines 96, 99, 103 (several .../directorymanager/11_0/... links)

Consider repointing these to the 11.1 equivalents. This is a content-adjacent cleanup, not a code correctness defect.
