Migration Utility export is corrupt

Situation:

After creating the offline export using the Migration Utility, the generated zip file is corrupted

I ran the migration utility by choosing standalone build->migration->offline migration->Export Without Logs->Selected Source->Selected->yes to optional files

Cause:

This could be due to a large number of files in the repository directory

Workaround:

The repository directory is defined here - Administer > Setup > Application Settings > Update System Properties > Kernel Settings > abpm.repository.root

1) Ensure all running flows are executed on the source environment
2) Move all the files from the source repository to a backup location
3) Delete all the files in the repository location
4) Run the export of the source environment
5) Once completed, restore the files to the repository location
