Kopano

Migrating Kopano is a multi-step process which also depends on the configuration of the backend used by Kopano.

If Kopano uses LDAP, the high-level view of the migration is as follows:

  • Configure grommunio appropriately to LDAP (settings user filters, etc.)

  • Create stores in grommunio

  • Migrating user data (which this article covers mainly)

  • Switch mail-routing

This migration focusses mainly on the migration of the dataset and does not imply an active LDAP configuration.

Important

This guide is not conclusive and is provided for convenience reasons. There might be aspects of your Kopano installation which is not covered by this manual. Please refer to your partner or feel free to contact us, specifically Professional Services for extended inquiries if you are missing something relevant to your migration.

Preparation

When migrating Kopano, being well-prepared matters. For this to happen, we need to make sure that the relevant metadata for migration is prepared, ideally in a list format which we can use to create our users in the grommunio installation:

kopano-admin -l | sed -e '1,4d' -e '/^$/d' | awk '{ print $1 }' | sort | while read user; do kopano-admin --details $user; done | egrep '^(Username|Fullname|Emailaddress|Store GUID| Warning| Soft| Hard)' | sed -e 's#^ ##g' -e 's#^Username:\t*##g' -e 's#.*:[\t ]*#;#g' | sed ':a;N;$!ba;s/\n;/;/g' >> kopano-users.txt

This (long) command executed on the Kopano system will create us a list of users with the important metadata of users which we will require in a format which can be used for further scripting.

With this list now, we can create the used domains in grommunio:

MAX_USERS_DOMAIN=250

cat kopano-users.txt | awk -F\; '{ print $3 }' | awk -F@ '{ print $2 }' | sort | uniq | sed '/^$/d' | while read DOMAIN; do
        grommunio-admin domain create -u ${MAX_USERS_DOMAIN} $DOMAIN
done

On the grommunio system, Kopano databases can be imported on the command-line with gromox-kdb2mt and gromox-mt2exm. These are two commands meant to be chained together by way of a pipe; tend to the linked manual pages to read about the invocation syntax.
