OakConstraint0100 while pre-upgrade step in AEM 6.4 upgrade
Hi All,
I am getting below error while running the PreUpgradeTask by invoking runAllPreUpgradeTasks() method :
com.day.cq.wcm.core.impl.VersionManagerImpl Unable to purge version 1.* for /<path> : OakConstraint0100: Item is protected: <path>
What could be the possible reason and solution?
