PEGA 8.7 can read BLOB created at PEGA 7.3?

I have some cases that were created in pega 7.3 in a table that i use as a purge and sometimes we retrieve the purge case to open and see the blob information.

This year i will update the platform to version 8.7. 
Can this BLOB that was created in PEGA 7.3 be read in PEGA 8.7 without problems? 
Are both blobs compatible?

i found this

Regarding BLOB Version for Pega 8.2 | Support Center.

and i understood that Pega8 is fully compatible with both version 6 and 7 of the storage stream.

Just need a confirmation or if is there any important issue to handle.

@FranciscoH6181 I think there’s been no change in the compressed format. See the question Regarding BLOB Version for Pega 8.2 , Extracting BLOB Content from Work Table and How to read BLOB pzpvstream from our production database

Current documentation is under Hybrid data storage model (pzPVStream BLOB)

Please have a look at some additional information that covers the 8.7 Archiving mechanism in forum question Purge and Archival strategy and Archive/Purge outside Work Class

@MarijeSchillern,

thanks for the answer, my conclusion is that version 7.3 and 8.7 use the same storageVersion 7. 
So in theory it will be possible to open the blob created in 7.3 in version 8.7 without problems.
