Users do not like change if they have been using a tool / web for quite some time. In order to make a tool scalable, how to change the behaviours of users who are already using product for some time.
Switching a user from one service to another is a tedious exercise. But nothing can be taken into granted by the marketers. User behaviour can be changed by creating dissonance in user's mind that may be from any source. Consumers/users usually give it a try to another product/service whenever they feel confused about the product they have been using.
Therefore, confused the users through some marketing promotions and let them experience dissonance.
demonstration of the product would help the consumer to understand the product better. For example, a person who has been using a feature phone would find using a cell phone with touch screen difficult. So, demonstration of this product will help to diffuse the market. Refer Roger (1962) Diffusion of Innovation for more info.
I'm disagree to your statement. as consumers always need something new and better. If it is provided in a user friendly way they are all set to use it. Just be innovative yet simple, in product as well in introducing the same.

We need to consider the range of experiences of people when using our products — understanding what nudges them to begin caring, take action, and stay motivated and engaged over time.
Ergonomically design plays an important role in the acceptance of a product. We need to offer free to use or try before using a product. Say we ask the person to try a car before buying. Similarly, we allow software to use 30 days free before buying. These kind of marking tricks will play prominent role in changing the behavior of a person on the product to use.
This phenomenon is quite frequent in disability, people cling to their old LightWriter and do not easily buy a new one with SMS functions, for example. Those functions, by the way, do cost serious money.
It reflects in a way that people claim ownership of what they have. I suspect that if you pay the customers to take part in improving it, they will be glad to use it. Possibly sell it, but not necessarily pay more themselves. Reasonable, in my opinion, as clients often are, in my limited experience.
Users frequently have a fair degree of time spent in learning the use of a specific tool. So they don't like investing more time in learning another tool. The question now becomes what is in it for them to spend the time. When they do not understand the value of the new product they will resist change.
Simply stated: "What is in for them?" it is not what you think about the new features but what they feel about them.
