Migrating from Zimbra to Gmail manually involves a few steps. Here's a general outline of what you need to do:
Export your Zimbra data: You'll need to export your Zimbra data into a format that Gmail can read. You can use the "Export" feature in Zimbra to create a backup of your mailbox data in a .tgz file.
Extract the data: After you've exported the data, extract the contents of the .tgz file to a folder on your computer.
Convert the data: You'll need to convert the data from Zimbra's format to Gmail's format. You can use a third-party conversion tool like Aid4Mail or Transend Migrator to do this.
Import the data into Gmail: Once you've converted the data, you can import it into Gmail. You can use the "Import mail and contacts" feature in Gmail to upload your converted data.
