Sharepoint migration Temporary storage on your local computer is too low.

During SharePoint migrations, the Microsoft tool provided sets up a temp folder under C:\Users\%USERNAME%\AppData\Roaming\Microsoft\, which ideally, at minimum, has 150Gb of space available. Due to many server setups, you can find that you receive the error saying Temporary storage on your local computer is too low with the error code 0x02010023. Below is how to fix and work around it.

You can try clearing up space on C Drive or move the Migration folder. To move the migration folder, you will need to make a link to another drive.

How to work around

Please note that screenshots don’t show the correct path, just the command.

  1. Run command prompt as admin
  2. make a new folder on your preferred drive with space: mkdir x:\MigrationToolStorage
Sharepoint migration Temporary storage on your local computer is too low. 1
  1. cd into the current location of your migration folder: cd C:\Users\%username%\AppData\Roaming\Microsoft\SPMigration\Logs\Migration
Sharepoint migration Temporary storage on your local computer is too low. 2
  1. rename your current storage location: rename MigrationToolStorage MigrationToolStorageOld
Sharepoint migration Temporary storage on your local computer is too low. 3
  1. make a symlink: mklink /D MigrationToolStorage x:\MigrationToolStorage
Sharepoint migration Temporary storage on your local computer is too low. 4

You should now be able to continue your migration. If you can not rename or create the folder, first stop the service ‘SharePoint Migration Service’
