+# Analytics SDK Java - Deprecation Notice
+
+**Status**: ⚠️ **DEPRECATED** - Effective August 31, 2026
+
+---
+
+## Important Notice
+
+The **FactSet Analytics SDK for Java** (`com.factset.analyticsapi:engines-sdk`) is **officially deprecated** as of **August 31, 2026**.
+
+### Timeline
+
+| Date | Status | Action |
+|------|--------|--------|
+| **Until Aug 31, 2026** | Active | Limited security fixes only |
+| **Aug 31, 2026** | Final Release | Last day of support - FINAL DATE |
+| **Sep 1, 2026+** | Removed | ALL versions removed from Maven Central - Enterprise SDK REQUIRED |
+
+### What This Means
+
+✅ **Existing Projects**: Continue to work (installed before Sep 1)  
+❌ **New Projects**: Cannot install Analytics SDK from Sep 1, 2026 onwards  
+❌ **New Installs**: IMPOSSIBLE after Aug 31, 2026 - Enterprise SDK ONLY  
+⚠️ **Security Issues**: NO patches after Aug 31, 2026  
+🔄 **Migration REQUIRED**: Must complete migration by Aug 31, 2026
+
+---
+
+## Migration Required
+
+### Why Migrate?
+
+- **Long-term Support**: Enterprise SDK is the actively maintained solution
+- **New Features**: Enterprise SDK receives regular updates and features
+- **Security**: Security patches provided for years to come
+- **Support**: Dedicated support team for enterprise deployments
+
+### How to Migrate
+
+#### Step 1: Review Current Usage
+
+```java
+// Identify all code using the Analytics SDK
+import com.factset.analyticsapi.engines.api.*;
+import com.factset.analyticsapi.engines.model.*;
+```
+
+#### Step 2: Update Project File
+
+```xml
+<!-- OLD: Analytics SDK (Deprecated) -->
+<dependency>
+    <groupId>com.factset.analyticsapi</groupId>
+    <artifactId>engines-sdk</artifactId>
+    <version>6.3.1</version>
+</dependency>
+
+<!-- NEW: Enterprise SDK -->
+<dependency>
+    <groupId>com.factset.sdk</groupId>
+    <artifactId>FactSetAnalyticsAPI</artifactId>
+    <version>1.0.0</version>
+</dependency>
+```
+
+#### Step 3: Update Imports
+
+```java
+// OLD: Analytics SDK
+import com.factset.analyticsapi.engines.api.*;
+import com.factset.analyticsapi.engines.model.*;
+
+// NEW: Enterprise SDK
+import com.factset.sdk.FactSetAnalyticsAPI.api.*;
+import com.factset.sdk.FactSetAnalyticsAPI.model.*;
+```
+
+#### Step 4: Update API Calls
+
+Refer to the [Migration Guide](./MIGRATION.md) for specific API changes.
+
+### Installation Methods
+
+**Maven:**
+```xml
+<dependency>
+    <groupId>com.factset.sdk</groupId>
+    <artifactId>FactSetAnalyticsAPI</artifactId>
+    <version>1.0.0</version>
+</dependency>
+```
+
+**Gradle:**
+```gradle
+implementation 'com.factset.sdk:FactSetAnalyticsAPI:1.0.0'
+```
+
+---
+
+## Key Dates
+
+### FINAL DATE: August 31, 2026

+# Migration Guide: Analytics SDK → Enterprise SDK (Java)
+
+**From**: com.factset.analyticsapi:engines-sdk (Deprecated)  
+**To**: com.factset.sdk:FactSetAnalyticsAPI (Recommended)  
+**⚠️ CRITICAL**: All Analytics SDK versions removed from Maven Central on Sep 1, 2026
+
+---
+
+## Quick Start
+
+### Step 1: Update Project File
+
+**In your pom.xml:**
+
+```xml
+<!-- REMOVE -->
+<dependency>
+    <groupId>com.factset.analyticsapi</groupId>
+    <artifactId>engines-sdk</artifactId>
+    <version>6.3.1</version>
+</dependency>
+
+<!-- ADD -->
+<dependency>
+    <groupId>com.factset.sdk</groupId>
+    <artifactId>FactSetAnalyticsAPI</artifactId>
+    <version>1.0.0</version>
+</dependency>
+```
+
+Or via CLI:
+
+```bash
+# Remove old
+mvn dependency:tree | grep analyticsapi-engines-sdk
+
+# Remove in pom.xml, then add new dependency
+```
+
+### Step 2: Update Imports
+
+Find and replace in your code:
+
+```java
+// OLD
+import com.factset.analyticsapi.engines.api.*;
+import com.factset.analyticsapi.engines.model.*;
+
+// NEW
+import com.factset.sdk.FactSetAnalyticsAPI.api.*;
+import com.factset.sdk.FactSetAnalyticsAPI.model.*;
+```
+
+### Step 3: Update API Calls
+
+Refer to specific API sections below for changes.
+
+---
+
+## Namespace Mapping
+
+| Analytics SDK | Enterprise SDK |
+|---|---|
+| `com.factset.analyticsapi.engines` | `com.factset.sdk.FactSetAnalyticsAPI` |
+| `com.factset.analyticsapi.engines.api` | `com.factset.sdk.FactSetAnalyticsAPI.api` |
+| `com.factset.analyticsapi.engines.model` | `com.factset.sdk.FactSetAnalyticsAPI.model` |
+| `com.factset.analyticsapi.engines.client` | `com.factset.sdk.FactSetAnalyticsAPI.client` |
+
+---
+
+## API-Specific Migration
+
+### PA Engine API
+
+**Before (Analytics SDK):**
+```java
+import com.factset.analyticsapi.engines.api.PAEngineApi;
+import com.factset.analyticsapi.engines.model.PACalculationParameters;
+
+PAEngineApi apiInstance = new PAEngineApi();
+PACalculationParameters paCalculationParameters = new PACalculationParameters();
+String result = apiInstance.postAndCalculate(paCalculationParameters);
+```
+
+**After (Enterprise SDK):**
+```java
+import com.factset.sdk.FactSetAnalyticsAPI.api.PAEngineApi;
+import com.factset.sdk.FactSetAnalyticsAPI.model.PACalculationParameters;
+
+PAEngineApi apiInstance = new PAEngineApi();
+PACalculationParameters paCalculationParameters = new PACalculationParameters();
+String result = apiInstance.postAndCalculate(paCalculationParameters);
+```
+
+### SPAR Engine API
+
+**Before (Analytics SDK):**
+```java
+import com.factset.analyticsapi.engines.api.SPAREngineApi;
+import com.factset.analyticsapi.engines.model.SPARCalculationParameters;
+
+SPAREngineApi apiInstance = new SPAREngineApi();
+SPARCalculationParameters sparCalculationParameters = new SPARCalculationParameters();
+String result = apiInstance.postAndCalculate(sparCalculationParameters);
+```
+
+**After (Enterprise SDK):**
+```java
+import com.factset.sdk.FactSetAnalyticsAPI.api.SPAREngineApi;
+import com.factset.sdk.FactSetAnalyticsAPI.model.SPARCalculationParameters;
+
+SPAREngineApi apiInstance = new SPAREngineApi();
+SPARCalculationParameters sparCalculationParameters = new SPARCalculationParameters();
+String result = apiInstance.postAndCalculate(sparCalculationParameters);
+```
+
+### Vault API
+
+**Before (Analytics SDK):**
+```java
+import com.factset.analyticsapi.engines.api.VaultApi;
+import com.factset.analyticsapi.engines.model.VaultCalculationParameters;
+
+VaultApi apiInstance = new VaultApi();
+VaultCalculationParameters vaultCalculationParameters = new VaultCalculationParameters();
+String result = apiInstance.postAndCalculate(vaultCalculationParameters);
+```
+
+**After (Enterprise SDK):**
+```java
+import com.factset.sdk.FactSetAnalyticsAPI.api.VaultApi;
+import com.factset.sdk.FactSetAnalyticsAPI.model.VaultCalculationParameters;
+
+VaultApi apiInstance = new VaultApi();
+VaultCalculationParameters vaultCalculationParameters = new VaultCalculationParameters();
+String result = apiInstance.postAndCalculate(vaultCalculationParameters);
+```
+
+---
+
+## Configuration Changes
+
+### Authentication
+
+Both SDKs use similar authentication patterns:
+
+```java
+// Analytics SDK
+ApiClient defaultClient = Configuration.getDefaultApiClient();
+HttpBasicAuth basicAuth = (HttpBasicAuth) defaultClient.getAuthentication("basicAuth");
+basicAuth.setUsername("username");
+basicAuth.setPassword("password");
+
+// Enterprise SDK (same pattern)
+ApiClient defaultClient = Configuration.getDefaultApiClient();
+HttpBasicAuth basicAuth = (HttpBasicAuth) defaultClient.getAuthentication("basicAuth");
+basicAuth.setUsername("username");
+basicAuth.setPassword("password");
+```
+
+---
+
+## Building and Testing
+
+### Build the Project
+
+```bash
+mvn clean package
+```
+
+The compiler will show warnings for any remaining old SDK references.
+
+### Run Tests
+
+```bash
+mvn test
+```
+
+Verify all tests pass with the new SDK.
+
+### Address Compiler Warnings
+
+If you see warnings like:
+```
+[WARNING] com.factset.analyticsapi.engines.api.PAEngineApi is deprecated
+```
+
+Make sure you've:
+1. Removed all old package references
+2. Updated all import statements
+3. No old SDK code remains
+
+---
+
+## Troubleshooting
+
+### Problem: "Cannot find symbol 'PAEngineApi'"
+
+**Solution**: Verify package is installed:
+```bash
+mvn dependency:tree | grep FactSetAnalyticsAPI
+```
+
+Should show: `com.factset.sdk:FactSetAnalyticsAPI`
+
+### Problem: "Package com.factset.analyticsapi.engines does not exist"
+
+**Solution**: Update import statements:
+```java
+// Change from:
+import com.factset.analyticsapi.engines.api.*;
+
+// To:
+import com.factset.sdk.FactSetAnalyticsAPI.api.*;
+```
+
+### Problem: "Cannot resolve method"
+
+**Solution**: Clear Maven cache and rebuild:
+```bash
+mvn clean install -U
+```
+
+### Problem: "Artifact not found"
+
+**Solution**: Verify Maven Central has the new package:
+```bash
+# Check if package is available
+mvn dependency:resolve -DincludeClassifiers=sources
+```
+
+---
