Effort needed to migrate from QlikView to Tableau depends on the way your QlikView software is implemented. In some cases, the data needed for QlikView Dashboard is completely prepared in a 3rd party tool so when migrating to Tableau, you do not need to convert ETL (extraction - transformation - load) code. But in most cases, ETL for QlikView is implemented using Qlik's own query language, AQL (QlikView is based upon patented technology called Associative Query Logic (AQL)).
Tableau does not provide a native ETL functionality so when migrating from QlikView to Tableau, you will probably need a 3rd solution to implement ETL for Tableau.
The exception above is of course keeping QlikView for ETL and just converting QlikView in-memory data to Tableau's native data set, TDE. But this usually involves, keeping two software licenses under maintenance.

1 - Selecting an ETL tool to migrate QlikView AQL code to
2 - Migrating QlikView AQL code to new ETL logic
3 - Reimplementing the dashboards
Yes, there is no product/tool that does automatic migration from Qlikview to Tableau dashboards. You need to manually implement the dashboards in Tableau. Traditionally, QlikView scripting language is richer than Tableau's own expression language so you will also need to handle some in dashboard calculations in ETL when migrating to Tableau.
Though looks difficult, the task is achievable, especially if you outsource the Qlikview to Tableau migration work to a company who knows both QlikView and Tableau. Here is one such company.
