Antigravity IDE 2.0 Migration & Recovery: The Complete Step-by-Step Guide

The release of Antigravity IDE 2.0 introduced changes to default registries, user settings structures, and workspace management. While these updates bring speed and parity improvements, many developers experienced lost extensions, broken terminal setups, or auto-update loops during the migration. This comprehensive guide covers the step-by-step process to recover your configuration, restore the VS Code marketplace, and optimize your new IDE environment.

Step 1: Terminate Existing Processes

Before modifying configuration files, ensure that all active background processes are closed. Running update utilities in the background can lock directories and corrupt active data folders.

• 1
  Completely shut down Antigravity, Antigravity IDE, and any active installer panels.
• 2
  Open Windows Task Manager (Ctrl + Shift + Esc).
• 3
  Search for and terminate any lingering instances of Antigravity.exe or Update.exe.

Step 2: Backup Existing Code Settings

Always create secure local backups before copying configuration scripts. Your original extension databases and workspace histories should be stored safely in a backup directory.

• 1
  Backup Extensions: Locate "C:\Users\Admin\.vscode\extensions" in File Explorer and copy it to a secure location.
• 2
  Backup User Data: Go to "C:\Users\Admin\AppData\Roaming\Code\User" and copy the files to preserve settings.json, custom keybindings, and snippet templates.
• 3
  Export Extension Lists: Run "code --list-extensions > vscode-extensions.txt" in your VS Code terminal to generate a complete backup manifest of your extensions.

Step 3: Restore the Official VS Code Marketplace

By default, Antigravity IDE 2.0 points to the OpenVSX extension registry. Since many proprietary, company-backed, or specialized extensions are missing from OpenVSX, you can configure your IDE to query the official Microsoft Marketplace repository.

• 1
  Inside Antigravity, go to Settings -> Antigravity Settings -> Editor.
• 2
  Locate "Marketplace Item URL" and set it to: https://marketplace.visualstudio.com/items
• 3
  Locate "Marketplace Gallery URL" and set it to: https://marketplace.visualstudio.com/_apis/public/gallery
• 4
  Fully restart the IDE to refresh the extension query registries.

Step 4: Automated PowerShell Migration Script

Instead of manually matching directories, you can copy your user profile, snippets, global states, and settings from the old Antigravity instance to the new IDE setup using PowerShell. Run PowerShell as an Administrator and execute the migration script below.

• 1
  Define the source registry path: $src = "C:\Users\Admin\AppData\Roaming\Antigravity\User"
• 2
  Define the target workspace path: $dst = "C:\Users\Admin\AppData\Roaming\Antigravity IDE\User"
• 3
  Create directories: New-Item -ItemType Directory -Force -Path $dst
• 4
  Copy settings: Copy-Item -Path "$src\settings.json" -Destination $dst -Force
• 5
  Copy bindings: Copy-Item -Path "$src\keybindings.json" -Destination $dst -Force -ErrorAction SilentlyContinue
• 6
  Copy snippet templates: Copy-Item -Path "$src\snippets" -Destination $dst -Recurse -Force -ErrorAction SilentlyContinue
• 7
  Copy workspace cache: Copy-Item -Path "$src\workspaceStorage" -Destination $dst -Recurse -Force -ErrorAction SilentlyContinue
• 8
  Copy extensions: Copy-Item -Path "$src\globalStorage\*" -Destination "$dst\globalStorage" -Recurse -Force -ErrorAction SilentlyContinue

Step 5: Copy Extension Directories Manually

If certain extensions do not automatically render after running the user settings migration, copy the local extension library directory directly between the directories. Run the following command in PowerShell:

• 1
  Execute: Copy-Item "C:\Users\Admin\.antigravity\extensions" "C:\Users\Admin\.antigravity-ide\extensions" -Recurse -Force
• 2
  Restart the IDE to force it to re-parse the extensions list.

Step 6: Resolve Common Post-Migration Bugs

After copying configuration directories, check for typical post-migration issues such as lag, blank terminals, or auto-complete failures.

Restore Language Server (LSP) and Auto-complete Stability

If language servers like PHP Intelephense or ESLint crash constantly after the migration, their databases may be corrupted. Clear the workspace index cache by closing the IDE, deleting all folders inside "C:\Users\Admin\AppData\Roaming\Antigravity IDE\User\workspaceStorage", and relaunching. The IDE will perform a clean rebuild of your project indexes.

Fix Integrated Terminal and Shell Launch Errors

If your built-in terminal opens to a blank screen or shows path errors, navigate to settings, search for Default Profile: Windows, and set it to PowerShell. Make sure your shell paths are correctly formatted without conflicting nested settings.

Step 7: Disable Forced Auto-Updates

To prevent future updates from silently overwriting your customized registry settings or breaking active extensions, you can disable the auto-upgrade tool.

• 1
  Navigate to your local installation directory: C:\Users\Admin\AppData\Local\Programs\Antigravity
• 2
  Locate the update executable: Update.exe
• 3
  Rename the file to: Update_DISABLED.exe

By locking down the update mechanism, manually managing your extensions, and pointing to the official VS Code marketplace, you get the performance advantages of Antigravity IDE 2.0 while keeping a stable, reliable environment.
