+# ASP.NET Boilerplate v5+ to ABP Framework Migration
+
+ABP Framework is **the successor** of the open source [ASP.NET Boilerplate](https://aspnetboilerplate.com/) framework. This guide aims to help you to **migrate your existing solutions** (you developed with the ASP.NET Boilerplate framework) to the ABP Framework.
+
+## Introduction
+
+**ASP.NET Boilerplate** is being **actively developed** [since 2013](https://github.com/aspnetboilerplate/aspnetboilerplate/graphs/contributors). It is loved, used and contributed by the community. It started as a side project of [a developer](http://halilibrahimkalkan.com/), but now it is officially maintained and improved by the company [Volosoft](https://volosoft.com/) in addition to the great community support.
+
+ABP Framework has the same goal of the ASP.NET Boilerplate framework: **Don't Repeat Yourself**! It provides infrastructure, tools and startup templates to make a developer's life easier while developing enterprise software solutions.
+
+See [the introduction blog post](https://blog.abp.io/abp/Abp-vNext-Announcement) if you wonder why we needed to re-write the ASP.NET Boilerplate framework.
+
+### Should I Migrate?
+
+No, you don't have to!
+
+* ASP.NET Boilerplate is still in active development and maintenance.
+* It also works on the latest ASP.NET Core and related libraries and tools. It is up to date.
+
+However, if you want to take the advantage of the new ABP Framework [features](https://abp.io/features) and the new architecture opportunities (like support for NoSQL databases, microservice compatibility, advanced modularity), you can use this document as a guide.
+
+### What About the ASP.NET Zero?
+
+[ASP.NET Zero](https://aspnetzero.com/) is a commercial product developed by the core ASP.NET Boilerplate team, on top of the ASP.NET Boilerplate framework. It provides pre-built application [features](https://aspnetzero.com/Features), code generation tooling and a nice looking modern UI. It is trusted and used by thousands of companies from all around the World.
+
+We have created the [ABP Commercial](https://commercial.abp.io/) as an alternative to the ASP.NET Zero. ABP Commercial is more modular and upgradeable compared to the ASP.NET Zero. It currently has less features compared to ASP.NET Zero, but the gap will be closed by the time (it also has some features don't exist in the ASP.NET Zero).
+
+We think ASP.NET Zero is still a good choice while starting a new application. It is production ready and mature solution delivered as a full source code. It is being actively developed and we are constantly adding new features.
+
+We don't suggest to migrate your ASP.NET Zero based solution to the ABP Commercial if;
+
+* Your ASP.NET Zero solution is mature and it is in maintenance rather than a rapid development.
+* You don't have enough development time to perform the migration.
+* A monolithic solution fits in your business.
+* You've customized existing ASP.NET Zero features too much based on your requirements.
+
+We also suggest you to compare the features of two products based on your needs.
+
+If you have an ASP.NET Zero based solution and want to migrate to the ABP Commercial, this guide will also help you.
