I have SharePoint 2010 farm where there are custom workflows created for a few applications running on different site collections. I need to migrate the entire site collection along with the custom components (webparts & workflows) to a new SharePoint 2010 server farm.
To my current understanding , I'm planning to follow these steps to achieve the same , however I am not sure if I am missing something over here or if this is going to work or not.
NEW FARM
1) Create a new web application
2) Create a new site collection by attaching the content database from the old farm. This content database will have the site collections and the workflow instances.
3) Deploy all custom wsps necessary for the web parts and workflows.
4) Activate features on the new site collection by site actions > site settings > site collection features.
Please suggest if the above sequence of activities is correct or not. Are there any chances of things breaking or loosing workflow instances from one SharePoint 2010 farm to another by following the above method.
