But things are not that easy. I have found some problems and incompatibilities I wish to resolve.

1. Virtualmin configuration creates one main user for each domain and then subusers. The difference lies in the structure of the user name. For example if I create, I create automatically the unix user example, but if I want to add users to that domain those are created as user.domain in order to allow different domains have a user with the same name.

How can I ensure ISPConfig will do the same?
ISPConfig uses user prefixes and not user suffixes, you can not change that but you can remove the user prefix to migrate the old usernames and then activate the user prefix again.

2. Virtualmain adds apache stanzas in httpd.conf while ISPConfig add the per domain stanzas are added in a separate file in the vhosts folder. I did start ISPConfig and started creating domains but I found my older domains already defined as VirtualHosts in httpd.conf would not show up but a message generated by ISPConfig. A shared IP error. I did turn ISPConfig off, but the error remained, until I restored the old httpd.conf file and restarted Apache.
How can I avoid that problem. I saw in another forum that I had to give the internal network address of my host and not the external. But I use an external server and I don't know it.
remove your old vhosts from from your httpd.conf before you create the websites in ISPConfig. If you use an external server that is not in a NAT enviroment, you must use the external IP address.

3. As with email I used postfix, ISPConfig replaces in the following order: virtual_alias_maps = hash:/etc/postfix/virtual
which points at my actual email accounts by
virtual_maps = hash:/etc/mail/virtusertable

Would not it be possible to define /etc/postfix/virtual as the virtual_maps value for my mails, does virtusertable have the same structure than /etc/postfix/virtual created by virtualmin?
I dont know if ISPConfig uses the same structure for the virtusertable. If you want to migrate to ISPConfig you will have to create all users again in ISPConfig so it does not matter if the files have the same structure.
