+The script checks the presence of deprecated hardware in the fabric.
+
+The list of supported and unsupported hardware is populated from the Release Notes across all ACI releases. This means the check covers hardware compatibility changes introduced in any version, not just the most recent release. As new release notes are published and hardware is deprecated, this list is updated accordingly.
+
+Refer the [Release Note 15.0(1) of ACI switches][3] to see the list of unsuporrted hardware for your desired target versions. Prior upgrading to target version, replace the unsupported hardware elements in your fabric with other supported hardware.

 Contact Cisco TAC to remove any identified misconfigured objects before performing the upgrade to prevent policyelem crashes.
 The [CSCwd40071][68] defect affects versions 5.2(5c) and later with a fix available in 6.0(1g). However, the issue will only be triggered during Apic upgrades crossing 6.0(4c) due to [CSCwh80837][67].

+### Svccore Excessive Data Check
+
+Due to excessive `svccoreCtrlr` or `svccoreNode` managed objects, Apic gui stuck in loading multiple queries.
+
+The svccoreCtrlr and svccoreNode objects represent core files related to Apic and Leaf/Spines process respectively.
+
+Due to [CSCws84232][67], the APIC GUI may become unresponsive after login, with dashboards stuck in a continuous “Loading…”state.
+Administrators may be unable to access or operate the APIC GUI, potentially impacting day-to-day management or upgrade.
+
+This check will verify the count of the `svccoreCtrlr` Managed Object and raise and alarm with the bug if object count found more than 240. Remove the content or objects of `svccoreCtrlr` or `svccoreNode`. Contact Cisco TAC or upgrade to a release containing the fix for CSCws84232 before proceeding with an upgrade.
