My notes, things I have learned, and documentation I have created.

CentOS 7:

As the user on the machine where the keys are that you want to migrate:
Export the public keys:

gpg -a –export >mypublickey.asc

Export the private keys:

gpg -a –export-secret-keys > myprivatekey.asc

Export you trust database:

gpg –export-ownertrust > mytrust.db

Copy the mypublickeys.asc, myprivatekeys.asc and mytrust.db to the new machine.

Log into the new machine as the user you want the keys for:
Import the private key file:

gpg –import myprivatekey.asc

Import the public key file:

gpg –import mypublickey.asc

List the secret keys to verify:

gpg -K

List the public keys to verify:

gpg -k

Import the trustdb:

gpg –import-ownertrust mytrust.db

I was trying to use New-MailboxImportRequest to import a PST file into a mailbox. From EMS, I kept getting the following error:

“The term ‘New-MailboxImportRequest’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again”

I had to enter the following to get the necessary permission:

New-ManagementRoleAssignment –Role “Mailbox Import Export” –User UserImporting

I did this for the Administrator account, so:

New-ManagementRoleAssignment –Role “Mailbox Import Export” –User Administrator

Then, I was able to import the PST mail. With following command the email was put back into the same folder as when the mail was exported:

New-MailboxImportRequest -Mailbox mailboxname -FilePath UNCToFile

I imported the PST into a mailbox with an alias of jim:

New-MailboxImportRequest -Mailbox jim -FilePath \\SERVER1\c$\jim.pst

To install the public release key:

rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

This allows you to install from the local source. For me, I had copied all the packages from the RHEL5 CDs to a directory to use “yum localinstall.” Importing the key as outlined above enabled me to install the packages without getting the following error:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 37017186
