I am back with some good to know information as always 😜.
Now a days its common for a Qlik project to be migrated to Qlik Sense, at least the UI. I have been
involved in such projects but I felt the below challenges…
1. Should the data model also be migrated to Qlik Sense ?
2. What about the features that are there in QlikView and not there in Qlik Sense ?
3. On the whole how about the reload time in Qlik Sense ?
4. How about the reduction of files into multiple files using Qlik QMC balanced using Qlik Sense QMC like Simple reduction or Loop & Reduce ?
My experience is as below
1. Should the data model also be migrated to Qlik Sense ?
Per now Qlik is providing Dual license for both QlikView and Qlik Sense so architects are in no position to disturb their bigger data models to be migrated into Qlik Sense. So what is the process here?
Data model will be still in QlikView but it is binary loaded into Qlik Sense for UI development.
2.What about the features that are there in QlikView and not there in Qlik Sense ?
Thanks to Qlik for introducing a lot of features in Qlik Sense for the past 1 year or so but earlier it was a bit difficult to mimic the same look and feel in QlikView to Qlik Sense as there were no options or alternatives for getting them, but because of extensions this can be leveraged a bit but be careful to use them as they may not be trusted all the time to be intact with the latest version of Qlik Sense.
On the whole what I can say is we have to find new ways of presenting data to the user in Qlik Sense for scenarios where we don’t have substitutes for QlikView like Hide & Show Mechanism.
3.On the whole how about the reload time in Qlik Sense ?
There is a lot of difference in this aspect and at times Qlik Sense may crash if the load time of the app is more.
What I can suggest regarding this is to have a data model in QlikView and do a binary load in Qlik Sense, if there is no Qlik View at all then plan to have multiple Transform apps for the same.
There is no way that this can be achieved using Qlik Sense QMC, the only way that can be used is
-> Create multiples apps with same UI and data model but use the expressions accordingly to limit the values
-> Create multiples apps with same UI and expressions but create multiple versions of reduced data models in QlikView and then use them in UI apps of Qlik Sense.This way works when your project is having both QlikView and Qlik Sense but the first option should be used if your data model and UI is also built in Qlik Sense.
Hope this helps for migration of projects….
