Problems with overwriting the versions Nintex Workflow

 I wanted to modify a workflow, but I didn't want my modifications to overwrite the existing version,

so when saving I unticked the relevant checkbox.

I thought that this checkbox will come back next time but it is not there anymore for that particular workflow. 

And now, when I tested and published, I want to have the possibility to overwrite the existing version with new one,

but instead I have to save a new unpublished version, publish it, and delete the old one, which is not the best way.

So, the question is, how to get the checkbox back?

 

Resolution steps

 

(List Settings -> Workflow Settings -> Remove a workflow) and set all previous workflow versions to No New Instances and left only the most recent version as Allow. 

Upon doing this, I was again able to edit an existing workflow, publish it with overwrite, and see only the latest version on the Start a New Workflow page.

Note, if you select to Remove previous workflow versions, I believe it deletes them presently and you can no longer view the workflow history diagram on historical items that used this workflow version.

 

Looping in a Nintex Workflow running slow

Not sure if I understood completely, but I will say that the Pause action defaults to 5 minutes, even if you set it for say 1 minute. 

This can be changed internally within SharePoint but messing with the timer in such a way isn't really recommended as it can cause other issues.   

What you might be able to do is introduce the Pause Action after X amount of items, so maintain a Counter and then Run If counter = say 25,

then Pause for 5 minutes.  In this way you can control the amount of Pauses that take place and ultimately lower the amount of time this process takes.
