| 20 | .SH NAME | |
| 21 | exim_convert4r4 \- Convert Exim configuration from v3 to v4 format | |
| 22 | .SH SYNOPSIS | |
| 23 | .B exim_convert4r4 | |
| 24 | ||
| 25 | .SH DESCRIPTION | |
| 26 | This script is provided to assist in updating Exim configuration files. | |
| 27 | It reads an Exim 3 configuration file on the standard input, and writes a | |
| 28 | modified file on the standard output. | |
| 29 | It also writes comments about what it has done to the standard error file. | |
| 30 | It assumes that the input is a valid Exim 3 configuration file. | |
| 31 | A typical call to the conversion script might be | |
| 32 | ||
| 33 | .I exim_convert4r4 < /etc/exim/exim.conf > /etc/exim4/exim4.conf.new | |
| 34 | ||
| 35 | The output file | |
| 36 | .B MUST | |
| 37 | be checked and tested before trying to use it on a live system. | |
| 38 | The conversion script is just an aid which does a lot of the \(lqgrunt | |
| 39 | work\(rq. | |
| 40 | It does not guarantee to produce an Exim 4 configuration that behaves | |
| 41 | exactly the same as the Exim 3 configuration it reads. | |
| 42 | ||
| 43 | Each option change in the new file is preceded by an identifying comment. | |
| 44 | In fact, the conversion script tends to make quite a mess of your | |
| 45 | configuration, and you should expect to go through it afterwards and tidy | |
| 46 | it up by hand. | |
| 47 | ||
| 48 | Unless you are running a very straightforward configuration, the automatic | |
| 49 | conversion is likely to generate a non-optimal configuration. | |
| 50 | You should not only check it thoroughly, but also run as many tests as you | |
| 51 | can, to ensure that it is working as you expect. | |
| 52 | In particular, you should test address routing, using \-bt and \-bv, and the | |
| 53 | policy controls, using \-bh. | |
| 54 | If possible, you should also do some live tests (i.e. send and receive | |
| 55 | some messages) before putting Exim 4 into service. | |
| 56 | ||
| 57 | If you have a very complicated configuration, it is possible that | |
| 58 | exim_convert4r4 will break it in some situations, which is why thorough | |
| 59 | testing is strongly recommended. | |

| 62 | This manual page needs a major re-work. If somebody knows better groff | |
| 63 | than us and has more experience in writing manual pages, any patches | |
| 64 | would be greatly appreciated. | |
