I am migrating data from a 5.6.3.4 install to fresh install of 5.8 on localhost.

I have done this before with c5.6 > c 5.7

Following the links here and insturctions:https://www.concrete5.org/index.php?cID=710973...

However C5.6. thorws and error on package install asking for 5.6.3.5b1

and the C5.8 install does the smae but wants v 8.2.0a1 which isn't out as far as I can see.

Can you let me know where to find both versions of C5? or what to do otherwise.

Thanks
