Changing numbers of Db's and Fc's

Hello,

I have a S7-300 program with high FC and DB numbers.
Now I can't download this to an older CPU.
So I want to change the numbers to lower numbers.
Example: FC310 must FC5, DB534 must DB11, and so on.
Problem is when I do a block consistency check many errors are
appear,
So what is the right way to do this without making errors?
Something like symbolic programming?

Greetings,

Hi mulderm

How are changing the block numbers
could you post an example of the errors,

It's to difficult to let you show the errors.
Because it's a big program and maybe I did it wrong.

So how are you changing the block numbers, are you using the Rewire function

Also suggesting the re-wire option:

I will try the rewire option!
