Hi Zhang Huangbin,

I am preparing to migrate to a new server (Same OS).
The new server is a fresh install of iRedMail 0.9.8
The old server is 0.9.7 upgraded to iRedMail 0.9.8 as per upgrade doc:
https://docs.iredmail.org/upgrade.iredm … 0.9.8.html

I have done a recursive config file comparison prior to the data migration to pick up any local changes.
In doing so I have identified that epel.repo for the fresh install does not include "exclude=gnustep*"

After adding it in, I ran the following, to swap over to the SOGo Repo files.

yum downgrade gnustep-base*

Removed:
  gnustep-base.x86_64 0:1.24.9-1.el7
  gnustep-base-libs.x86_64 0:1.24.9-1.el7

Installed:
  gnustep-base.x86_64 0:1.24.6-6.el7.centos
  gnustep-base-libs.x86_64 0:1.24.6-6.el7.centos

As a side note: The old server with the upgraded iRedMail 0.9.8 was using the EPEL versions (1.24.9-1) too, and there did not seem to be any negative issue.
This would be because I ran yum update before upgrading to iRedMail 0.9.8, and adding in the "exclude=gnustep*".

This info is more for accuracy of the upgrade process to match that of a clean install -  Unless you know that the  "exclude=gnustep*" can be omitted.

Thanks, Rob.
