Final migration checks

1. Manual configuration migration

1.1. Re-apply out-of-the-box sensor packs changes

AppMon 2017 May Modifications to out-of-the-box sensor packs in the Server Settings > Sensor Packs > Edit dialog box (only possible in debug mode) are not migrated. Do not export and reimport these old sensor packs, but rather re-apply the edits in the UI.

AppMon 2018 April Configure these in Server Settings > Sensor Packs > Edit > Custom Extension.

If migrating from AppMon 2018 April to the same version or higher, these modifications are migrated automatically.

1.2. Check user plugins

In the AppMon Client: Settings > Dynatrace Server, if plugins installed by the user were not migrated, re-install them.

1.3. Reimport LDAP certificates

If an additional certificate for LDAP such as CA or a self-signed certificate is imported to the AppMon keystore:

  • server/conf/jssecacerts

Don't copy the old keystores, to avoid security issues through potentially compromised public certificates.

Re-import the previous certificate by logging on with an AppMon local user and click in the AppMon Client: Settings > Dynatrace Server > Users > LDAP > Test Connection.

1.4 Update server hostname

If the OS-hostname changed, manually update it.

1.5 Re-enable automatic agent updates

If you disabled automatic agent updates before the upgrade, once Server and all Collectors are upgraded, re-enable the automatic updates.

1.6 Java cryptography policy

If you manually changed the Java cryptography policy of the shipped JRE on the old installation, also apply the changes in the new installation's JRE.

2. Confirm operation of the new AppMon Server

To ensure correct operation, verify that:

  • All Agents in the Agent Overview:
    • Are connected.
    • Have data coming in: scroll over horizontally to verify that Event Count or Class Load Count (or both) change.
    • Have the correct new Agent version and Update version if one was installed.
  • PurePaths come in.
  • Dashboards are properly displayed.
  • Historical data is present if you migrated the Session Storage. Otherwise check Settings > Dynatrace Server > Storage and verify that the directory points to your session storage data.
  • Test the WebUI (default port 9911), Server website (default port 8020) and REST services and check certificates if those were customized.
  • Verify that these services and connectors work: Email, LDAP, Proxy, DC-RUM, Gomez.
  • Run the UEM Health Check
  • Review the Start Center > Administration for errors or warnings.

Migration successful.
