Considerations for changing BlackBerry Dynamics certificates
    Review the following considerations if you want to change any of the 
BlackBerry
        Dynamics
 SSL certificates. If problems occur when you change a certificate, communication between BlackBerry UEM
 components and between UEM
 and BlackBerry
        Dynamics
 apps could be disrupted. Plan and test certificate changes carefully.| Consideration | Details | 
|---|---|
| Add new certificates to peripheral equipment | If you have added  BlackBerry
        Dynamicscertificates to peripheral equipment on your network, add the new certificate to peripheral equipment before adding it to UEM. | 
| Use the latest versions of  BlackBerry
        Dynamicsapps | If you are replacing the  BlackBerry
        Dynamicscertificate for application management or Direct Connect, ensure that users are using the latest available version of BlackBerry
        Dynamicsapps before you replace the certificate. | 
| BlackBerry
        Dynamicsapps must be open to receive a certificate | A user must open a  BlackBerry
        Dynamicsapp on their device for it to receive a certificate from UEM. If you are replacing the BlackBerry
        Dynamicscertificate for application management or Direct Connectand the change becomes effective before UEMpushes the certificate to all BlackBerry
        Dynamicsapps, any apps that did not receive the certificate must be reactivated. Apps do not receive certificates while they are suspended on iOSdevices or while Androiddevices are in Doze mode. | 
| Verify that the  BlackBerry Connectivity Nodeis accessible | If any  BlackBerry Proxyinstances are unreachable by UEMwhen BlackBerry
        Dynamicscertificates are replaced, BlackBerry
        Dynamicsapps will not be able to connect to those instances following the certificate replacement. | 
| Scheduling certificate changes | If you are replacing the certificate for  BlackBerry
        Dynamicsservers, choose a period of low activity to restart the servers. Allow sufficient time for new certificates to propagate to  BlackBerry Proxyand BlackBerry
        Dynamicsapps. If you are replacing only the certificate for BlackBerry
        Dynamicsservers, allow at least 10 minutes before the server restarts. |
