Cb content

Hi, i have a site made in 1.5 and i´m migrating to 3.9 the original site use cb 1.9 and Cbsubs 2.0
On several page have the code {cb: [username]} and similar with package and other things.
I see now the {cb: } is no needed that make the site show {cb: Name of member}
Is there a way to change all that only show Name of member?
Is a large site and have many content to change 1 by one.
Is possible?

The old {cb}SUBSTITUTIONS{/cb} usage still works, but is no longer needed. There's no support for {cb:SUBSTITUTION} so if that's what you're using you'll need to replace those usages. Easiest way to do that is probably directly in your database using SQL string functions, which you can review below.
