Best way / tools to migrate master to new hardware

Hello Team,
I have already looked around in the forum and found e.g. https://www.howtoforge.com/communit...n-a-multi-server-setup-to-new-hardware.73513/.
However, since I did not find answers to all my questions, I would like to open a new post here ;-)
I have an ISPconfig Multiserver Setup. Master with most services except mail. Mail is on a slave server.
Now I have to migrate the master to a new hardware. Unfortunately I will lose my IP in the process.
The question now is: What is the best way to migrate to the new hardware and what tools will help best?
1. where on the master/slave do I have to replace the old master IP with the new master IP?
2. which tool do I use to migrate everything to do with ISPconfig from the old to the new server? "Migration Tool" or ISPCopy?
3. is there a guide somewhere for this kind of scenario?
I know that I have to set up the OS on the new server according to the old master server (I will do this using the related "Perfect Server Setup").
Thanx for your great support ;-)
Kai

 

The slave mail server will stay, only the master will be migrated to new hardware. So, I use the ISPCopy, right?
For changing the IP: are the information from https://www.howtoforge.com/communit...n-a-multi-server-setup-to-new-hardware.73513/ still valid?

• The /usr/local/ispconfig/server/lib/config.inc.php should contain the hostname, not the IP. So altering this file should not be required.
• In the MySQL database on the master, there you can find the ispcsrv[ID] user that this slave uses to connect twice, once with the hostname (does not need to be altered) and once with the IP (needs to be altered). The best way is to use the user editor of phpmyadmin to do that as the permissions are a bit complicated and splitted to various sub tables and the user editor in phpmyadmin handles this for you so you, so just change the Ip with the user editor.
• If this node is a web server and you used the IP instead of * in websites, then you have to change the IP in ispconfig under System > IP addresses (or better add the new one and leave the old one there until you changed the sites) and then select the new IP in all websites that use it.

Is there anything additional to be changed on the mail-slave? E.g. in the local mysql on that server?

 

Hi, I bought the current migration tool today - which is also including ISPcopy. Reading the README.txt I am now a little bit confused:
"
ISPCopy can also be used to move a slave node within
a multiserver system to a new server, this can't be done with
the Migration Tool.
"
Does this mean, I can't use the tool to migrate the MASTER to a new hardware?
+ can someone answer my question regarding the needed IP changes from my previous post?

 

Thanx everyone! Will try to do the migration tonight

 

Hi all, I now prepared everything for the migration of the master node. But, isp_copy is not working at all ;-(
Everytime I try to start the tool, a get an error (after inserting my license key):
"Missing php-json module"
My machine is using debian buster and old server + new server are setup in the same way.
php default is 7.3 - but I also tried installing php7.1 on the old master node because related to https://www.howtoforge.com/communit...ter-server-to-a-new-server.83363/#post-396814 it could be a problem with PHP version??

 

I will open a new ticket!

 

Hi again, migration is done and all DNS-settings should be changed to the new master IP. But now I have a new problem ;-(
Opening one of the URLs connected now to the new server, I get a server error:
Firefox: Fehlercode: SSL_ERROR_RX_RECORD_TOO_LONG
Chrome: ERR_SSL_PROTOCOL_ERROR
Any idea? Do I have to force renewing the letsencrypt certs on the new server?

 

Seems that using control panel Rsync tool solved the problem

 

Hi, my migration is done. Using ISPcopy worked quite will. There is just one point, I am a little bit unsure.
ISPcopy did NOT migrate the database users which are needed to connect from my mail server node.
I don't know which tutorial I used in the past, but looking around, I found the one from @till
https://www.howtoforge.com/multiser...se-servers-on-debian-squeeze-with-ispconfig-3
If I check the database setup on the first page, I can see only users for root being created.
Am I right, that this root-user should be used in /usr/local/ispconfig/server/lib/config.inc.php on the mail node?
//** Database settings for the master DB. This setting is only used in multiserver setups
$conf['dbmaster_type'] = 'mysql';
$conf['dbmaster_host'] = 'MAINSERVER-IP';
$conf['dbmaster_port'] = '3306';
$conf['dbmaster_database'] = 'dbispconfig';
$conf['dbmaster_user'] = 'ispcsrv3';
$conf['dbmaster_password'] = 'MYSECRETPASSWORD';
$conf['dbmaster_new_link'] = false;
$conf['dbmaster_client_flags'] = 0;

And it seems, the database connection has also to be defined in /usr/local/ispconfig/server/lib/config.inc.php

I'm asking, because I find the funny user ispcsrv3 in my config file, and restoring the user did some problems regarding the grants used on the old server ...
Using till's tutorial, the mysql-user root should be used, right?

 

Thanx till, this was really helpfull!! Should I remove the section from the config files first? Or will ispconfig_update reuse the settings (like password) from the config files?

 

Thanx till - this worked and the sipcsrv* users are back ;-)
