Importing intraday data from another provider, while using SierraCharts live intraday data

Support Request:

Hi,

I'm currently using a different provider that has provides intraday minute data a couple years back before SierraChart does. I would like to save those couple of years, cancel the feed, switch to sierra as my provider and import the historical intraday data back for those couple of years that you don't provide.

I have two main questions in regards to this:

1. Is there any issues with being connected to Sierra data while using those couple of years of saved as historical data to my symbols? I'm assuming Sierra will overwrite the save data, back to the point in which Sierra no longer provides data, and that is where my saved/imported data will start displaying?

2. What would constitute me having to re-import my saved historical data? For instance, if I "Delete All Data And Download" would that also delete the historical data that I had previously imported? And is there any other action that I may take that would cause me to need to re-import that saved historical data?

Please advise.

1. There is no problem with this. Sierra Chart is not going to overwrite any data.

2.
For instance, if I "Delete All Data And Download" would that also delete the historical data that I had previously imported?
Yes it will.

And is there any other action that I may take that would cause me to need to re-import that saved historical data?
Any operation that will cause the data to be deleted or overwritten. For example what is documented here:
