Move configuration

Hello, i would like to ask you if there is any way how to move configuration from 1100 to 1100AH. I read multiple posts but none anwser my question.

  1. Without any knowledge i just did binary backup and move it to second one, but this totally broke up interfaces on 1100AH RB (my friend told me this works fine only when you have same routerboards). After this i wound following information:

The configuration backup can be used for backing up MikroTik RouterOS configuration to a binary file, which can be stored on the router or downloaded from it using FTP for future use. The configuration restore can be used for restoring the router’s configuration, exactly as it was at the backup creation moment, from a backup file. The restoration procedure assumes the cofiguration is restored on the same router, where the backup file was originally created, so it will create partially broken configuration if the hardware has been changed.

  1. Export command on 1100 helps me a bit, i replaced /interface ethernet a vlan section with old configuration from 1100AH. I used dialog System Reset Configuration with after reboot action where i selected modified *rsc file. After i rebooted 1100AH the routerboard was reset to default. Thats weird so after this i called /import file=*rsc which successfully loaded configuration but it stack on information login already exists.

Can somebody help me pleas with this problem? Any hint will be greatly appreciated.

Best regards

use /export compact
It will export only made changes.

Thank you. This is very nice new feature but I still have problem with loading configuration:

Opening script file compact-1100.rsc
Script file loaded successfullyfailure: such login name already exists

This is part of configuration where i found keyword: login

add backup-allowed=yes disabled=no login=admin parent=admin password="" \
    paypal-accept-pending=no paypal-allowed=no paypal-secure-response=no \
    permissions=owner signup-allowed=no time-zone=-00:00

Before i load this configuration i reset RB to non-default configuration

One hint for compact export. There would be nice to define ethernet by name (ether1) instead of number cause when I move configuration from 1100 to 1100AH there is problem with switching groups cause:

RB1100

0 - ether12
1 - ether13
2 - ether11
3 - ether6
4 - ether7
5 - ether8
6 - ether9
7 - ether10
8 - ether1
9 - ether2
10 - ether3
11 - ether4
12 - ether5

RB1100AH

0 - ether12
1 - ether13
2 - ether1
3 - ether2
4 - ether3
5 - ether4
6 - ether5
7 - ether6
8 - ether7
9 - ether8
10 - ether9
11 - ether10
12 - ether11

So instead of

set 4 master-port=ether6

use

set ether7 master-port=ether6
