Hi, everyone.
Had a conversation with HC2MM team and gathered the following gotchas when using the tool besides the ones listed in documentation:
- Migration moves all Hipchat users, both active and inactive. Make sure to configure Mattermost instance for Max Users Per Team setting to be equal to or exceed the number of total users in HipChat.
- Copy the executable file to any machine that can access both your Hipchat server and your Mattermost server. The directory on which the executable is saved and run is referred to as WORKING_DIRECTORY. Please make sure the user launching the application has write access to this directory .
- Please make sure there is enough disk space for the export file and the server has sufficient memory (at least 16GB).
