# Running the IC2 → IC3 Migration Tool

## This article outlines the full process for preparing, backing up, and running the migration tool to migrate your IntranetConnections IC2 environment into IC3.

#### **2. Back Up Your IC3 Environment**

Perform a complete backup prior to migrating.

### **Steps**

1. Turn **off IIS**.
2. Create the following folder: `C:\temp\Backup`.
3. Copy the following into the backup folder: 
     - `C:\storage` → `C:\temp\Backup\storage`
     - `C:\inetpub\wwwroot\SITE`  
       `C:\inetpub\wwwroot\SITE-API`  
       → `C:\temp\Backup`
4. On SQL Server, generate a **full database backup** of the IC3 database.  
   Save as: `C:\temp\Backup\IC3.bak`
5. Turn **on IIS**.

#### **2. Patch IC3 to Version 3.1.1‑rc07**

Before beginning the migration, ensure the IC3 environment is patched to version **3.1.1‑rc07**.

### **Steps**

1. Turn **off IIS**.
2. Open Windows PowerShell and navigate to:  
   `C:\temp\IC3` (or wherever your `download.ps1` script is located).
3. Run the following command: .\\download.ps1 -instanceName "SITE\_NAME" -version "3.1.1-rc07"
4. Turn **on IIS**.
5. In a browser, open:  
   `https://[SITE_NAME-API].[DOMAIN]/Setting/LoginProviders` 
     - If `"isSuccess": true` appears, the deployment is successful.
6. Verify the IC3 version at:  
   `https://[SITE_NAME].[DOMAIN]/`  
   Ensure the version displays **3.1.1‑rc07**.

#### **3. Migration Preparation**

Gather and stage all required IC2 files and data.

### **Steps**

1. Create a **full SQL backup** of the IC2 “IntranetConnections” database from the IC2 server.
2. On the IC3 SQL Server: 
     - Create a new database named **IC2**.
     - Restore the IC2 backup into this database.
3. Copy the IC2 **Intranet folder** (turn off Lucee and IIS first) to:  
   `C:\temp\MigrationFiles`
4. If the IC2 Documents folder resides on another drive, copy the **documents** folder into:  
   `C:\temp\MigrationFiles`

---

#### **4. Launch the Migration Tool**

1. Open a browser and navigate to the migration page:  
   `https://[SITE_NAME].[DOMAIN_NAME]/migration`
2. Enter the **LegacyAppConnectionString**, using the format below:

### **Example Connection String**

```
Server=[SERVERNAME];Initial Catalog=[IC2_DB_NAME];Persist Security Info=False;User ID=sa;Password=[SA_PASSWORD];MultipleActiveResultSets=False;TrustServerCertificate=True;Connection Timeout=30;
```

### **Sample**

```
Server=localhost;Initial Catalog=IC2;Persist Security Info=False;User ID=sa;Password=123456Ab!;MultipleActiveResultSets=False;TrustServerCertificate=True;Connection Timeout=30;
```

1. Set **LegacyAppFilesPath** to:  
   `C:\temp\MigrationFiles`
2. Click **Next**.

---

#### **5. Select and Migrate Applications**

1. Click **Open Application List…**
2. Check all IC2 applications you want to migrate.
3. Click **Next**.
4. Click **Migrate** and allow the migration to complete without interruption.
5. When the **Migrate** button becomes clickable again: 
     - Confirm the migration status shows **Complete**.
