Currently my WealthLab is installed in : C:\Program Files\Fidelity Investments\Wealth-Lab Pro 6
Wealth Lab Developer is installed in : C:\Program Files\MS123\Wealth-Lab Developer 6
The data is located in : T:\TRADING\PLATFORMS\WealthLabPro\1.0.0.0\Data

I forgot how I put the data folder (I think hard linking).

T:\TRADING\PLATFORMS\WealthLabPro\1.0.0.0\Data\FidelityStaticProvider has four folders
"5 minute", "15 minute", "30 minute" and "Daily"
and the total size is 9.57GB

There is another folder
T:\TRADING\PLATFORMS\WealthLabPro\1.0.0.0\Data_Relocated\FidelityStaticProvider
which has 30.4GB of data.

When I run the Data Migration Tool which folder will be the source of the data and which folder will be the target. ? Can I change the target to "T:\TRADING\PLATFORMS\WealthLabDev6\Data\ instead of "
"C:\Program Files\MS123\Wealth-Lab Developer 6\Data"

The Fidelity data is not migrated. There's no provider to read it in WLD. But you can try out workarounds e.g. How-To: Migrate your intraday Fidelity data to AlphaVantage.

P.S. In a later build of the Migrator, we have plans to convert Fidelity DataSets (but again, not the data itself) into IQFeed, Yahoo and Wealth-Data (with regard to specific Fidelity symbols that translate into different ones).

Where is the Fidelity data stored ? Is it in

T:\TRADING\PLATFORMS\WealthLabPro\1.0.0.0\Data\FidelityStaticProvider

OR

T:\TRADING\PLATFORMS\WealthLabPro\1.0.0.0\Data_Relocated\FidelityStaticProvider

It's your computer, what do I know.

Just FYI, this doesn't make sense. The latter folder is not used by WL to keep user's data. It merely contains some preset files (strategies, rules, DataSets, markets) used to initialize an installation.

@Eugene, the Fidelity provider had an option to relocate the Fidelity cache.

Right, but since he mentioned hard linking that is done by the user on his own in Windows...

WealthLab Pro stored data in
"C:\Users\<Windows User Name>\AppData\Roaming\Fidelity Investments\WealthLabDev\1.0.0.0\Data"

Does Wealthlab developer use the same location to store downloaded data ?

I hardlinked the "C:\Users\<Windows User Name>\AppData\Roaming\Fidelity Investments\WealthLabDev\1.0.0.0\Data" to "T:\TRADING\PLATFORMS\WealthLabPro\1.0.0.0\Data\FidelityStaticProvider"

Wealth-Lab Pro Data folder was:
"C:\Users\<Windows User Name>\AppData\Roaming\Fidelity Investments\WealthLabPro\1.0.0.0\Data"

Wealth-Lab Developer Data folder is:
"C:\Users\<Windows User Name>\AppData\Roaming\Fidelity Investments\[WealthLabDev\1.0.0.0\Data"

Thanks for the update.

I have around 9GB of Intraday data from Fidelity in Wealthlabpro. How do I transfer it over to WealthLab dev ?

No need to transfer over because I'm not aware of a provider that can read it. Is there one?

Follow up...
Of course one can be created somewhat easily, but I think ideally we could eventually provide an option to use and even update Fidelity data using a different provider, like IQFeed. I've gotta think about that one!

Try the AlphaVantage provider. It will read the data.
