187 + <h3>Why should XWiki be upgraded regularly?</h3>
188 + <p>
189 + XWiki should be upgraded regularly to reduce security exposure, keep extensions compatible, avoid large
190 + upgrade gaps and make long-term maintenance easier. Regular upgrades are easier to plan and validate than
191 + major jumps after several years.
192 + </p>
193 +
194 + <h3>Is a working XWiki instance safe to leave unchanged?</h3>
195 + <p>
196 + Not necessarily. An XWiki instance can continue to work from a user perspective while becoming outdated,
197 + harder to upgrade and exposed to avoidable risks. Visible functionality is not the same as long-term
198 + maintainability.
199 + </p>
200 +
201 + <h3>What should be checked before upgrading XWiki?</h3>
202 + <p>
203 + Before upgrading XWiki, review the current version, target version, intermediate upgrade steps, installed
204 + extensions, custom code, authentication setup, infrastructure, backups, rollback expectations and
205 + business-critical features.
206 + </p>
207 +
208 + <h3>Should an XWiki upgrade be tested outside production?</h3>
209 + <p>
210 + Yes. The safest approach is to rehearse the upgrade on a staging environment or temporary clone, fix
211 + compatibility issues there, then perform the production upgrade with a clear plan and rollback expectations.
212 + </p>
213 +
214 + <h3>What makes an XWiki upgrade difficult?</h3>
215 + <p>
216 + XWiki upgrades become more difficult when the version gap is large, extensions are outdated, custom code is
217 + undocumented, authentication is complex, infrastructure dependencies changed or critical workflows were not
218 + included in the validation plan.
